Ponysoft: Trilight Demo

Trilight Demo

This is a demonstration of a project I am working on. Maybe some of you heard about the project Trilight. I liked the idea and was looking forward to playing the game, but some time ago I found out the project was cancelled. So I decided that I could at least try to create a similar game, and after receiving an explicit permission from the original developer Michiel De Mey I started working on it. It is just a very basic demo, but I will do my best to make this a decent game.

Download the demo here

Recommended configuration: Windows XP with Service Pack 3 or higher (if an error pops up about missing "msvcp100.dll", you will need to install Visual C++ binaries)
Direct X 9.0b or higher

Also confirmed that it runs under Wine (tested on Ubuntu 12.10)

Installation: Just unpack the ZIP archive anywhere on your disk and run Trilight.exe

Can't play your demo. It says I need some d3dx10_43.dll or something.

Hi, the problem should now be fixed. As of now, the program only requires DirectX 9.
Once again, sorry for the inconvenience.

May I recommend packaging the .zip in a folder? I.e. instead of having /Trilight.exe and /data, have /Trilight/data and /Trilight/Trilight.exe ... that way it's easier for people to extract (they don't have to create another folder, they can literally extract it anywhere).

Gonna try the game soon, it looks awesome =)

EDIT: Can't play it... it hates my (standard, 1280x1024) resolution (and it screws up my screen badly). Could you _please_ provide an option to make it windowed when the full version comes out?

Thanks for your input! I'll repack it right away.
Sorry about the resolution problem, enabling a windowed mode is very much possible, I'll make sure the final version can do that. Did you manage to play the game or did it crash? The game should restore your original resolution if it tried to change it first, but maybe it didn't succeed for some reason.

"Did you manage to play the game or did it crash?" It does work, but I really don't like playing fullscreen games, because it takes a long time for me to fix the resolution once the game has ended (sometimes I even have to reboot). This is NOT a problem with your game, as it's with every single fullscreen game that changes the resolution to something smaller than my screen (there is an odd bug where you can scale the resolution down, but not up, so even if your game tries to restore the resolution, it won't work).

So if you can make it windowed, I'll love you forever =) Okay, I didn't mean it in THAT way, but, well, you know what I mean =P

Ah, glad to hear that. I tried to make sure that if the game does change the resolution, it restores it after you quit. Also, the demo only knows aspect ratios 4:3, 16:9 and 16:10, otherwise it tries to change your resolution to 1024x768 (4:3). I realize this is silly and in the final version it will be handled better.

Enabling windowed mode should be easy, because between you and me, the development builds already do run in windowed mode ;) I probably won't be able to rebuild this particular demo for windowed mode, because since I posted it (in march) the code has already changed, sorry about that.

If I may ask one more thing, what OS are you using?

I see, that's why it sent me that message. Was wondering what it was about =P

I'm using linux (arch linux). And if you're wondering, I'm using wine 1.6-80-gb6fc57e (latest git, as of 2 weeks ago) =)

That's great, tell me, did it appear as if the game is running much faster than it should? I tried running it in Wine and I discovered a bug in Wine's implementation of a certain Windows procedure that makes the game run too fast. If you are willing to help me, could you download this archive, run the programs ShowFPS.exe and ShowFPS_LINUX.exe in wine an tell me the numbers it will show?

Nope, it seemed normal (unless your game was supposed to be at half speed or something =P). For both ShowFPS.exe and SHOWFPS_LINUX.exe, I got a steady 60-62FPS, though that might also be because my graphics card has vsync turned on.

Also, I noticed that in the game, you seemed to have an object sorting issue (for example, if I'm on the ground, and there's a wall right beside me, and I move up and right, it will get stuck, instead of hitting the wall and sliding up)... are you using Box2D for the physics and CR? or using a custom-built one?

@scootadoo_t · 608 weeks ago

Interesting... I had about 400 fps in wine, but maybe I have an old version and since then the bug causing this has been fixed. Thanks for your help, this will help me ensure that the game runs well for everyone :)

Glad I could help! This game looks very promising already =D

Also yes, I am using Box2D and I know about those bugs, and even though I did my best to make it work sometimes it still derps a bit. I found a few other open source physics engines, so if it becomes too much of a problem I can try and use another one. How did you know it was Box2D? Is it known for these issues?

anonymousmeerkat 73p · 608 weeks ago

"How did you know it was Box2D?" It was kind of a wild guess, but it's the most popular 2D physics engine (by far). "Is it known for these issues?" It's a standard issue with CR, but I'm not sure why Box2D, with the popularity it has, hasn't fixed it yet (I'm guessing it's intentional, for some odd reason).

If this can help you, I've written a tutorial on how to fix it, but it's written for a custom-built AABB CR (i.e. game CR that is not in a library). I'm not sure if you'll find anything useful from it, but, well, if you can, awesome! http://mijyn.github.io/tutorial/2013/06/05/platfo... (the part in question is at the end, but you'll probably want to read most of it to understand how it works).

But since that only works for AABB (though it will work for non-AABB, it'll just be a bit buggy, in the same way as using an AABB algorithm to do CR on non-box objects would be buggy), what you'd have to do if you're not using AABB (which you're obviously not), is to replace all of the functions to their SAT equivalent (but since you're using an engine, you'll probably only have to code in `collides_by_axis`, if that), and, of course, use a loop instead of a simple `if (x && y)`.

Sorry, I know I'm being super-vague here, but it's kind of late, and I can't think properly. I hope this can help you though!

I played your demo and tested for bugs. Here's my thoughts (with screenshots): http://www.mediafire.com/view/ksygv9j1koyc704/Tri...

Hey look, Trilight's back! :D

I was kinda tempted to revive it myself (probably via JavaScript), but yours already looks pretty cool. Sucks that it needs DirectX (or Wine) to run, though.

Ditto on everything @EvdogMusic said. Also, I needed to run the demo with Compatibility Mode set to WinXP+SP3 on my Windows 8 machine. Otherwise, the title screen would flicker for a few seconds, then the application would mysteriously minimize itself. Probably not any fault on your part.

Is this still in development?
