Texture Mapping Question

I'm going to assume for now that your sprites are frames of animations. If this is the case, then it would be ineficient to change textures durring an animation. If I am wrong and they are just single animation sprites (173 individual images without any kind of animation), then you might want to group the sprites together based on the progress of your game. i.e. if the level your playing doesn't contain any carrots, or viles, or whatever your game sprites are, then don't include them into the texture for that level.

You lost me at the point precision however. If you have 10x10 sprites, then that means your texture coordinate offsets would be the result of 1.0f/10.0f. But if you want 20x20 sprites, then the texture coordinate offsets would be 1.0f/20.05. Of course at 20x20 your sprites would be half the size of the ones on a 10x10 scheme.

Ok, you seem to have lost me as well. Ok, Im talking about the sprites for just one of the characters so it won't contain any other sprites that are not specific to that character. My understanding of texture mapping is that all textures are mapped based on a 0.0f to 1.0f coordinate system. This means that 0.0f, 0.0f is the top left hand corner of the texture and 1.0f, 1.0f is the bottom right hand corner. Now with that in mind, the texture cordinates can never exceed 1.0f so they have to be split into fractions of that 1.0f ceiling. So then you are limited to 0.0f, 0.1f, 0.2f, 0.3f etc until you hit 1.0f. This means you can only map 100 sprites since your rows and collums of sprites can never exceed 10 (essentially a 10x10 grid of sprites). Now what I am asking is if there is any way to increase the precision of the texture coordinates to possibly make it accept 2 digits of precision so you could effectively have a 100x100 grid of sprites. Then the coordinates would be 0.00f, 0.01f, 0.02f, etc until you hit 1.00f. Does this make more sense? Let me know if I'm going about mapping my sprites/textures the hard way.

Why don't you use 0.05, 0.10, 0.15, 0.2... etc. to pull sprites out of your texture map? You can definitely index UV sampling coordinates with values that aren't always 0.1, 0.2, 0.3, etc.

Hmm, maybe I did something wrong but when I tried using 2 point of precision I got a white box instead of a textured box. I'll attempt it again and see what happens. I might have received some misinformation as to the bounds of texture mapping somewhere.

"Now what I am asking is if there is any way to increase the precision of the texture coordinates to possibly make it accept 2 digits of precision so you could effectively have a 100x100 grid of sprites."

It should be inherent. What function call are you using? Maybe show us a code snippet?
