shoot left when facing left, shoot right when facing right - HELP!

scitunes

I want to make an actor that shoots. When he is walking right or facing right i want the spawned bullet to fly right. When he is walking left or facing left I want the bullet to fly left.

What's the best way to do this?

Thanks!

I think there are already some posts delaing with this, but to make it quick: Create an attribute in the actor which switches if "key right" and switch to another state "if key left". Than create a rule which checks if this state is "1" or "0" and then spawn the bullet in angle 0 or 180. That should do it already

Thanks for the link, codemonkey. That makes sense. So when I use that method to check which way the actor is facing how do I get it to shoot in that direction. Do I create two different actors (bullet left and bullet right) and give each one a different direction in the accelerate behavior? Will all that spawning be a problem?

Thanks for the positive feedback!

Just make a variable and give it the 0 or 180 accordingly when you spawn the bullet. The bullet just needs a basic move behavior.

@scitunes: In regards to memory usage, if they don't have too many rules it should not be too much of a problem. Just don't go overboard. If you can make it one actor it would be better than 2. Just do as TheT suggests and use the expression editor to determine direction of the move or change velocity behavior. And don't forget to use a Change Image as well, if you need to show direction of the bullet.
