1. Load a custom sprite sheet using LOAD "GRP4:[nameOfFile]"
2. Use SPDEF to define the properties of the sprite.
3. Display the sprite using the definition number used on step 2.
Example:
VAR SP
LOAD "GRP4:MYSPRITES"
SPDEF 50,0,0,32,32,16,16,1
...
SP = SPSET(50)
If you are still learning, then this will probably make more sense.
SPSET 0,16,16,32,32
SPOFS 0,0,0,-10
In SPSET the first number is the management number, the two numbers after that are X and Y coordinates on the sprite sheet, (The starting point) and the last two are the ending point on said sprite sheet...I'm terrible at explaining things, but that's the easier version for beginners...
