Trials of Oryx

While I was looking at sprites for my rogue like game at Oryx Design Lab, it turns out that they’re doing a competition called Trials of Oryx which started on the day I started looking into doing the game, what are the chances?

I’ve taken this chance to accept the obvious fate and join in with the challenge. Could be tricky with a minuscule amount of free time I have for such things but perhaps it’s the inspiration I need to keep at it.

I’ll try to keep updates coming but for now, I’ve got a game to make =)

RogueLike

I love playing the majority of video game genres but think out of all of them, RPG games are probably my favourite game genre and delving down, rogues would have to be my favourite sub genre.

For those not in the know, rogue like games are classic dungeon crawlers which are randomly generated and notoriously difficult.

It’d been a while since I’d played one and once I’d delved in, I became obsessed. After a week of being reminded of the unforgiving difficulty it dawned on me that a started building a dungeon based game many moons ago. I checked my project folder to make sure it was still in existence, luckily it was.

Although it’s in the very early stages, the key functionality of the seeded random dungeon generator was pretty much in place. Other pieces in place is the beginnings of the path finding and sprite loading.

As you can see it’s all rather barebones, the same one sprite is used to represent the player and the enemies, stairs are yellow tiles & doors are green. Where I left it, it was mainly the dungeon generation which was being developed with everything else to be thought about later on.

I’m quite keen to pick this project up again so hopefully I’ll have more updates in the near future while the enthusiasm is in full flow =)

Game Development (October 2013)

Not too much has changed over the last couple of months, nothing at face value at least. I’d been doing some testing of the game on a tablet and wasn’t completely happy with the city transition. On the mobile device there was a slight lag when moving between the city blocks as it was generating each city block instantly which had an effect on the performance. In usual cases this would be solved by threading but unfortunately in AS3, threading is currently only available in beta for android applications and currently in development for iOS.

After some time thinking of solutions I came up with changing the city generation from using standard loops which would run through everything there & then to using the game’s frame rate as the loop instead. This would result in spreading out the processing over multiple frames allowing to maintain a good FPS. The only drawback of this method is that it will take longer for the city blocks to be generated which shouldn’t cause too much of an issue, the city will be large enough that the generation would have finished long before the player reaches the edge of the city.

There’s been two other relatively small changes, the first is random buildings which is quite significant for a random city generator. The second change was so buildings at the edge of city blocks get grouped together into one building instead of fragments.

random city buildings

 

This is a rough example just implementing the classes used for the city. The different coloured squares represent the different building types and the roads poking out the sides are the roads which link up to neighbouring blocks.

Back in the zone

For the last couple of months I’ve decided to take a step back from the game development and work on a new site. When progress seems to stand still for too long I tend to shift onto something else temporarily which usually leads to it ticking over in the back of my mind.

In the mean time I created a new site for snippets (www.snippola.com)… not really relevant but more of a shameless plug =)

Anywho, while working on the site I was also thinking about the game and have made yet another u-turn and decided to go back down the 3D route. I’ve thought of a way to turn it into more of an action RPG style game which should also help preserve the survival aspects I’m wanting to maintain.

Upon getting back into the 3D game development state of mind and starting to implement these new ideas, it dawned on me that there were a couple of underlying issues with the setup of my existing work. Although I did spend a little while trying to correct these issues, the decision was made to start afresh & gradually import the existing work into the new workflow.

Although there’s nothing much to show at this point, there should be soon =)

Game Development (June 2013)

Well it doesn’t really feel like there’s been huge leaps & bounds in anything to see over the last month but the basis of some pretty important pieces have been put into place. http://youtu.be/uHIM6X9JUHc Please note that the video is also zoomed out to what it will be, this is purely to show how the tiles are working. The first noticeable change will be the buildings but they’re merely placeholders for something better which is why they look pretty flakey. They’re currently created based on individual tiles which won’t really work as a whole as they’re going to need to know which building type they’re part of and which tile of that building. There’s also the issue where buildings at the edge of a city section have a wall through the middle. The next thing to notice would be the enemies are back, even if they are very basic in their current state. At present there’s a set limit of five which will randomly spawn on the level load and respawn when they’re knocked off the map. They move very linearly, as in a randomly picked direction and they’ll travel in that direction non-stop unless you get close enough for them to follow you. They can also be targeted and attacked by the player, though this is a very primitive process as it currently stands. What’s Next? Like I mentioned earlier, the buildings really could do with a lot of work but at this point I’m thinking that the basics of different building types would be good to get in place. Another important item on the todo list is obstacles and let the player walk through walls =)

A new perspective

After spending an excessive amount of free time trying to get 3D picking to work without any success I decided to go back and revisit the original plan.

When I first started out planning this game I was originally torn between two very different directions. Firstly there was a more old-school type RPG style using point & click on an isometric field. The other was more of an action RPG where the player would be in direct control of their character. Originally I was leaning towards the isometric as I thought it would work better on touch screen devices and there were certain aspects of gameplay could be integrated. For example, I wanted ammunition to be relatively scarce and for the player to weigh up using valuable ammo from a safe distance or going in for a melee attack. I think this idea works better in a classic RPG style due to weapon familiarity could then be added to provide better accuracy and damage.

Although I preferred isometric and thought it would work better, I chose to go with a top down approach purely out of laziness which was probably a bad step. I knew that if I used a top down setup then it would allow me to adopt a GTA style of sprites where only one direction would be needed and rotated. The isometric view would however need a different graphic for each direction.

During working on the isometric tiles I revisited the AS3 graphics API which I’ve not really looked at much for the last few years and there are a few neat feature which have been added in. One which I’m now using is the ability to use texture triangulation on the 2D canvas in the same way you would in the 3D stage. This means that I can reuse my road texture which could create all road tiles from just one square image.

You may be wondering what’s going on with the tiles, the lime green & white set is the old tiles which was loading in each city block as it was in the 3D version. The dark green tiles is using a new technique which consists on only 100 tiles which dynamically update their positions and tile types based on the player’s position. Doing it in this manner should be more memory friendly as there will be less creating / removing and fewer tiles overall.

Random City Generator Code

I’ve been meaning to release the code for my random city generator for a little while now but just hadn’t got round to it…. UNTIL NOW!

Now I’m not saying this is the best or most efficient method for doing this, this is just the method I’ve created. Below is an interactive version of the generator, click on it to create a new city.

[swf:https://defenestrate.me/wp-content/uploads/2013/04/City.swf 201 201]

As you can see, far from perfect but it does the job. There’s still the issue of two lanes of road running next to each other but this is something I can live with

Dynamic Roads & Picking

It’s been a slow couple of weeks on the game development front which has mainly been down to trying to get ‘picking’ to work. I was thinking about the game play style and think that I’d prefer it to be more strategic than action and decided to change it to a point & click style game. This would also be a better choice as its mainly been aimed for mobile devices.

The main issue with this decision is that because I’m using a 3D environment now, I need to use a process called picking. Picking is the process when you click on a position of the screen and it calculates which object in the 3D environment has been clicked. This is all new to me and left me feeling quite out of my depth. I did manage to find an example of picking but it didn’t play nicely with my current workings when trying to add the methods to my code. After a full week of free time hours try to getting this working, I admitted defeat which doesn’t happen too often. The decision was made to take a look into a premade 3D engine so I started looking at Away3D.

Away3D

Looking at the examples on the Away3D shows that picking is alive & kicking and having a quick go at creating a testbed seems like a quick & easy solution to creating a 3D environment. My first issue was that there’s not really a great number of tutorials and the genreal help seems to be lacking, that is unless you want to pay for their support or purchase a book. At this revelation, the tenacious side of me kicked in again and I’ve decided to take another look at getting my own version working but in the mean time, take a break & make progress in other areas.

Dynamic Roads

While looking into the picking, I came to the realisation that the different sections of roads being used could be generated from just one tile. Being that the 3D models use triangulation, I could create a tile which would contain two different elements which could be manipulated to the correct road layout.

road

When applying the texture to the mesh, I have control over which part of the texture gets applied to which corner of the triangle. Therefore, with the image above I can create a straight section of road with the left triangle of the image twice or a crossroad using the right triangle in the same method. This in theory means that less textures are required and should help improve performance. The short video below shows this method in action.

It’s not the greatest looking piece of work but it’s functional and can be updated later on.

What’s Next?

There are a few pieces which are next on the list, I still need to get the picking working but I’ve pushed this to the back-burner for now so I can make some progress on other sections.

I really need to optimise the transition from one city area to another, currently there’s a lag when creating the new area which I really want to reduce or remove.

The other two sections are the pieces I really want to get my teeth into, that’s the enemies with basic reactions. The other is to make each city block more unique, I want there to be different building types and searchable items (crashed cars, bodies, containers, etc)

Seamless city generation progress

I’ve made the decision to change the loading of levels in the game. Originally the plan was to load each piece of the city at a time when you exited and entered a new area. In more recent games, gamers are more accustom for levels loading in the background making it a seamless experience, therefore, this is what I’ve attempted to go for.

To show how I’ve implemented this, I’ve zoomed right out to give  you an idea of the process being performed.

As you can see there’s still a little left to do, the buildings at the edge of each section is still full length which will lead to long buildings so I just need to half the width of these. There’s also a slight lag while each block is being generated. All in all, it’s not too far off what I was hoping to achieve, just needs a few tweaks.

Game Development (April 2013)

Once again, it’s been a while since I’ve posted anything but enthusiasm dwindled a bit a few months ago. A few changes have been made since the last update but nothing substantial. They pretty much cover what I was wanting to get done in the next stint but it hasn’t progressed much further than that. The main reason of the lack of progress is that I tried running the game on an Android Nexus and by the version of AIR available doesn’t support the 3D stage which is a bit of a major blow for trying to create a 3D game for AIR to be used on Android devices =P

Zombies!

I’ve added in basic randomised zombie sprites which are currently spawning on each road tile. At this point in time, it was mainly to get a sprite on stage with a randomly picked texture. They’re also shootable but hit-testing is a little hit & miss and needs tweaking. The next step for them is to be randomly spawning based on the player’s location and being destroyed once too far from the player. They also need to move (as zombies do), randomly at first but react to the player by noise and viewing angle.

Besides the zombies, I’ve also added in a slight camera chase so the camera movement is a little more fluid. I’ve tried to capture this in the video by starting & stopping but this may just end up being annoying. I’ve also added in a slight improvement on how the roads are being drawn on stage, now I’ve just got to replicate this on all the other models.

I’ve been trying again to get the 3D stage working on the Android but there’s been a security update which is causing problems so I can’t currently export onto the device. Hopefully I’ll crack it soon.

Update (2 minutes later)

Welllllll……. although I spent a couple of hours the other day fighting with AIR and Android and gave up in a sulk, I’ve just tried it again and it worked straight off the bat. Seriously, no changes to any configuration, literally plugged in the device & clicked debug.

Now this is working, I’m feeling a second wind coming on.
