The direction of the bullet has to be always horizontal?
Is there a way to make it vertical?

Are you asking how to make a bullet go straight up?

Attach this to it:
Code:
function Create(self)
    self.Vel.Y = 0 - self.Vel.X;
    self.Vel.X = 0;
end

I know it's kinda strange, but I want to create something like a light saber :D

Hmm... My script will send them straight up in the air, so it won't be pretty. Maybe if you just reversed X and Y you'd get a better effect.
Code:
function Create(self)
    self.Vel = Vector(self.Vel.Y, self.Vel.X)
end

Ok, let me try.

Remember it attaches to the bullet, not the gun.

Nah, it didn't work.

I tried also:
Code:
function Create(self)
    self.Vel.X = self.Vel.Y
    self.Vel.Y = self.Vel.X
end


But it didn't work either.

What did it do? Try:
Code:
function Create(self)
    local store = self.Vel.Y;
    self.Vel.Y = self.Vel.X;
    self.Vel.X = store;
end

Nothing. It just kept moving in the direction it should move normally.

It could be because it isn't actually given velocity until a short while after it's fired. Maybe...
Code:
function Create(self)
    self.waitTimer = Timer();
end

function Update(self)
    if self.waitTimer:IsPastSimMS(50) then
        self.Vel = Vector(self.Vel.Y, self.Vel.X);
    end
end

It didn't work, plus, I got an error =D

RTE Aborted! (x_x) (Note, this was during gameplay)
Abortion in file.\System\DDTError.cpp,line 109, because:
Assertion failed: Collision mismatch in MOPixel::ColideAtPoint!
The last frame has been dumped to "abortscreen".

I never saw an error like that. And never in game.
What the ♥♥♥♥ is going on in here?

I've only ever seen anything like that once, and that was when I made MOPixels collide with each other. It won't be that, though. I'm not sure why you're getting it.

Colliding? Between them?
Maybe it could be because I put HitMos and GetsHitByMos to 1.
I'll change that and check.
