Ok, my game now is 90% completed. The last thing (but also very important) is background for the screen. Would it slow down the game if i draw a big quad to fill the screen then apply texture to it? I tested in my computer and it still run normally, but when i tried in my school's computer: it's awful. So is there anyway i can create background without using "applying texture on quad" method?
Hard to answer based on the lack of information (what API? what else is being processed per frame grphaically?)
But in general I would say you should be able to to that no problem. There may be faster/better ways to do this depending on what you're using to accomplish the task, but it would take a pretty crappy computer to be unable to handle a single quad... Unless your resolution is insanely high and your texture is insanely huge and you're surpassing the Gfx cards abilities in fill rate, memory, or bandwidth. Unlikely.
Nah, the highest resolution of the texture i'm currently get to is 512 (no more). I'm using Opengl by the way. Besides, every object i create in my game will be delete out of memory when they are destroyed, so memory would not be a problem. Well, i'm choosing background for my game right now!!! (such a pain)
Probably the only speedup would be if certain parts of the screen are rarely changed. Then you can make seperate quads for those and update as neccesary
No hdragon, our schools computers graphics card just can't handle the stuff.
They just can't, it is something you'll have to deal with at school, just understand that it is ONLY that computer that sucks that bad.
A full screen texture quad should not be a problem on any computer...unless it is a school's computer. I use this effect for a lot of things including sun-glare effects and even the alpha blending does not seem to affect the framerate at all.
Cards do better with large quads (hence sky planes) than they do with highly tesselated quads.
i guess i have to deal with it at school then. So here is a screen shot i took. (the level still hasn't finished though).
I still think you need a 3d ship in there, and throw some lighting and bloom over it :D
That's an awesome background, man!
Where did you get it?
google: "space wallpaper" :D
It really lights up the whole screen isn't it
I think you stole that space ship too from some game on shockwave
Nope, i designed the ship. It took me month to modified from sketch to full body color. Here is the original sketch, you'll laugh at it.Quote:
