The u and v = correspond to the x and y offset in the TIM file, so each TIM file could = contain many sprites that can be accessed by setting the u and v values = to each sprites width (u) and/or height (v) offset. If the TIM file you = are using contains only 1 sprite set the u and v to 0. I have attached a = TIM file called bricks that contains 7 coloured bricks. I am using this = file in a breakout game, to change the brick colour I just set the value = u to 16 * the brick number (Black brick is 0, Red brick is 1 and so on). = The value 16 is each bricks width in pixels. Hope this helps, James PS. There may be an easie way to explain this but above is how I = understand u and v are used.

Hi, I'm no expert in the field of displaying = sprites on=20 the Yaroze but the u and v arguments allow you to set up numerous = sprites from 1=20 TIM file (this helps messing about with numerous TIM files). The u and v = correspond to the x and y offset in the TIM file, so each TIM file could = contain=20 many sprites that can be accessed by setting the u and v values to each = sprites=20 width (u) and/or height (v) offset. If the TIM file you are using = contains only=20 1 sprite set the u and v to 0. I have attached a TIM file called bricks = that=20 contains 7 coloured bricks. I am using this file in a breakout game, to = change=20 the brick colour I just set the value u to 16 * the brick=20 number (Black brick is 0, Red brick is 1 and so on). The = value 16=20 is each bricks width in pixels.

Hope this helps,

PS.

There may be an easie way to explain this but above is = how I=20 understand u and v are used.
