what i want my program to do is simply draw a series of sprites, in an order along an imaginary \'shelf\' starting from 0,0, right next to each other. each image is 78 x 149 in size. and i am using the dimensions themselves to determine the position with my nested for loops.

this is my code, i dont understand why these images are all being displayed on top of each other.

1. You don't have to load the same image three times. Just load it once.

2. You need to get rid of the backslashes in your image name. Only use them to specify a path to another directory.

3. The problem you're asking about is being caused by using the same variable name for two different purposes in your SPRITE command:

SPRITE temp, tempx, tempy, temp

The first "temp" is the sprite number. The second "temp" is the image number. You need to use two different variables.

That's actually a forum error. It seems to happen at random.

The image number shouldn't need to be a variable if you want to use the same image for all of them. Just put a number there.
