Directional Firing Help *Problem Solved*

[Arcade]

I was trying out some code to fire missiles using ONLY the joystick (up/down/left/right). I can get the missiles to fire without a problem, however, trying to cancel out the missile (aka make it disappear when you stop pressing a certain direction) is causing problems. I don't like the fact that when I stop pressing a certain direction the bullet just stays on screen until I press another direction again. I want them to disappear whenever I stop firing in a certain direction.

 

If I try something like:

 

if !joy0up then missile0x=0: missile0y=0: a=0

 

Then it will work fine for making the bullet disappear when I stop pressing up...however, pressing any other direction screws up the bullet. The bullets stop traveling and only go 2 to 3 pixles in front instead of firing as before.

 

Is there a way to use up/down/left/right to fire bullets but also be able to make the bullet suddenly disappear when you stop pressing on said direction? I've been tinkering with this for quite some time and I can't seem to get it to work.

Did you peruse the examples here (specifically)

Yeah I did that but sadly it won't work. I press my two buttons for directional firing and it works except the other three which again just go a few pixels and stay.

Also, you may want to post your code so peeps can see if it's a simple problem.

I actually found the fix! Thanks for your help! I had been using that example for HOURS trying to fix my code for one little thing, then all of a sudden I tried something (out of nowhere) and it worked!

 

Thanks again so much for your help! Seriously, when you posted the example I opened up the file again and found the fix. Had you not posted that it might have took me even more time! Oh man thanks so much!
