Reflecting projectiles...
 

I'm working with some projectiles and bouncing them off walls... I'm just having a little problem with it.

Basically, it's easiest to approach it ala Pong. If it hits the wall on it's x axis to flip it's x velocity, and the same for its y velocity. The only problem is that's kind of hard to detect with projectiles. At first I had it when it hit a wall to determine it's 'direction' using getdir and it's velocity, but when dealing with 45° shots, it tends to screw up because it's determining the wrong direction.
Any help here?

What I would do is just shoot the same projectile from the point of impact, so that it looks the same.

Also, I would suggest storing the angle on the player using a simple script:

Of course, That would store the angle of where the projectile is going and then you can use that to figure out what angle to shoot the new projectile.

I have all that being done. What's not being able to be done right is determining whether to inverse the x or y velocity because I can't figure out how to detect whether the projectile is hitting the wall on it's x or y axis.

Why not? the simplest solution in this situation would to be to set up two onwall checks in the shape of a cross through the ball. Then you would know which axis hit.

It's a projectile

Sorry I just woke up and took it out of context.
Make your own projectile via class? :D

onActionProjectile2(). You could find the right angles, then shoot() again in the right angle.

I already have the projectile worked out. It shoots back and all. I'm just having the problem of determining which side of the projectile actually hits the wall so I can reflect it properly.
And I dunno about the class thing, seems like a lot of effort and a lot less effecient to use a class.

a projectile is an object spawned with a clientside and serverside, it really is no different.

Yes, except that's way out of the way for something that's pretty simple and works in just about every way except for this one thing.
