Hello Agian
OK I have mange to get a space invader graphic andi have manag to move him to the left or right ut here my problem.

when my invader reaches the end of the screen i can not work out how to drop the invader down one line and them move him the opposite direction ? also my invader flases when he moves is this because of the loop in the program if so how do you stop the lashing?

cheers
Ian


`load your image first
load image "invader.bmp",1
letterX=300
letterY=200

do
cls


if letterX>0 then letterX=letterX-10
if letterX=0 then letterX=letterX+10
`if letterY>0 then letterY=letterY-1
`if letterY<0 then letterY=letterY+1
paste image 1, letterX, letterY
loop

I made a space invaders mock-up game using only primitives, you can have the code if you like, the only thing I didn't do was make the inavders "walk" back and forth, and down. In thinking about this I figured I'd use a couple of hidden objects that denote the outter point (width) of the group of invaders, checking for when they reach a certain horizontal position to cause the invaders to drop down 1 level...of course I never finished or implemented it, but the game is fully functional otherwise

to stop the invader flashing when it moves, try putting sync on at the top of the source and then just before loop try sync

e.g

`load your image first
load image "invader.bmp",1
letterX=300
letterY=200
sync on
do
cls


if letterX>0 then letterX=letterX-10
if letterX=0 then letterX=letterX+10
`if letterY>0 then letterY=letterY-1
`if letterY<0 then letterY=letterY+1
paste image 1, letterX, letterY
sync
loop
