Im making a space invaders style of game (atleast I think I am ) and somethings wrong. right now, the player can shoot, but the lasers and bombs dont go anywhere
the game calls a function primaryfire() (or secondaryfire() if its a bomb) when the player clicks, to place the sprites. The problem is it justs puts them there and they dont do anything.
after each game loop, the program calls a subroutine updatescr, which is SUPPOSED to reposition the laser sprites.

can someone tell me whats wrong?

Ok, im not too sure, but i believe its because your placing the sprite in the same position as it already was...

by doing:



You're just positioning it in the same place as i already was...

To fix it, you need to do something like:



Dont know if it'll work though...

Hope I Helped...

I tried that.... It didnt work so I tried putting the sprite x(50) and sprite y(50) into oldx and oldy....

The y part is in a different spot....
i have:
oldy-las(1)
for the y positioning, which is the old y location minus 14 or something.

Ahhh I figured it out!!! Its because some of the variables arent globals... I hate the way dbc cant use globals without arrays.
I just replaced the functions with subs and it works
