HEY! 8) I'm making this asteroids program where the space ship moves along the bottom x-axis and when you hit the "8" key on the number pad it shoots a little red lazer... Right now when i do that it makes one lazer and u haveto hold the key down to make it move... how do i make it so u press 8 once and it send a little red lazer moving straight up along the y-axis??? Thanks


elsif move = "8" then
Pic.ScreenLoad ("lazer.jpg", x9 + 25, y10, picCopy)
y10 := y10 + 10
end if
thats the script that makes it go up when u hold "8" help plz...

you can read a tutorial on processes. This way you can program lazer to run independantly of the rest of the program

a better way however would be to use hasch function and put the lazer in same loop

code:

loop

if hasch then %if button is pressed
getch(c)
end if

if lazeron = true then %if lazer is currently on screen
lazerY += 5 %move lazer
end if

%move spaceship here

end loop


hasch returns true if there's a key in input buffer. Using above code you can bypass getch if no key is pressed and execute the rest of your code without waiting to press a key. Thats how you code snake and/or pacman to keep on moving untill another buttom is pressed

if you want to have better results zip all of your files into one zip and add it as an attachement thus making it easier for us to run and compile the program while editing Wink .....i copied and pasted the code and it didnt even run.....the thing shut down due to too many errors j/k....i din realize u used pictures..but when i ran it its like "NO PICTURE THERE H0M0"
