I am trying to make my first program using AppGameKit, and I am having some problems. Its a simple program in which a sprite moves, but i cannot get it to move. Ive loaded in the image for it, but i feel like the image is not linked the the sprite name correctly. I was hoping if i post my code someone could help me out, thanks...

//rem load in images and sounds
LoadImage = (1, "KITTY.jpg")

//rem set up variable

1 = KITTY
KITTYXpos = 400

KITTYYpos = KITTYYpos -5

Welcome

Change this:

1 = KITTY

to:

KITTY = 1

and this:

SetSpritePosition (KITTY, KITTYXpos, KITTYYpos)
gosub moveplayer


to this:

gosub moveplayer
SetSpritePosition (KITTY, KITTYXpos, KITTYYpos)



Things should start to move!

Hi, thanks for the help, still having a problem though when I changed the code to

gosub moveplayer
SetSpritePosition (KITTY, KITTYXpos, KITTYYpos)

I am getting the error "moveplayer" is not a valid label. I dont know if I would be better trying to start the project again from scratch.

It looks like you have a space between the label and the ":"

Finally got it to work, thanks for you help. I ended up just starting again and writing it out again, and it worked for some reason this time
