hi
i'm trying to make a game where i have a box and i can move it with the arrow keys, and also want to move circles across the screen at the same time. when ever i try to do it, only the circles move. I was wonder if someone could explain to me how to do both at the same time.

and try to move it works
so i only can't move when this part comes in

that is because you have a bunch of loops with delays in them. It takes quite a while for those loops to finish, and you're not checking for any input while inside the loops.

oooo
i get what you mean
so you're saying that i need to get the program to check for inputs while the asteroids fall.
hmmm
how would i do that though?

step procedures
code:
loop
check input
you move 1 step
asteroid moves 1 step
end loop
currently you have your loops set up so that an asteroid would move from beginning to end before letting go of the controls. Try to figure out how to let the asteroid move just 1 step, let go of the controls, and resume from where it left of next time

i'm not sure of what you saying....
what do you mean by letting go of the controls?
do you mean that i should get the program to check for inputs constantly before each move of the asteroid?

not only check, but also process and move the user accordingly

so do you mean somthing like this?
code:
loop
if chars (KEY_UP_ARROW) then
if y2 < 380 then %stop from going off the screen
drawfillbox (x1, y1, x2, y2, 255) %to cover box
y1 += 5 %to move box
y2 += 5
drawfillbox (x1, y1, x2, y2, 0) %box
end if
