As my characters use 10 frames per animation, with 8 different angles, and a still frame for each angle, I've created an image that is 10 frames wide, and nine frames deep.
The command is: "create animated sprite 1, "aws.png", 10, 9, 1"
where "Aws.png" is the file's name.
the 10=number of frames horizontially,
and 9=the number of frames vertically
The animation plays from upper left corner to upper right corner, and then proceeds left to right as it goes vertically down the image.
You can animate in two ways...
1)Use the "Play Sprite Sprite#, Start Frame, End Frame, Delay Value" command.
2)Make a subroutine to time out the frames, and to use the "Set Sprite Frame Horizontal#, Vertical#" command.
I personnally use the 2nd method as it allows me to synchronize the sounds to the animation.
If I did this right, here's what MY character looks like:

Her name is Alana, as is the the game's.
