Spawning bullet at e.angle?

[Dare]

Well I want to spawn a bullet, that is rectangular in shape.

How do I spawn the bullet so it is at the same angle of the laser/box that is spawning it?

I'm sure there is some simple code.

Code: Select all

angle := math.atan(e.normal(1) / (e.normal(0) + 1)) * 2

Code: Select all

angle := math.atan(e.normal(1) / (e.normal(0) + 1)) * 2

aha, try this if e.normal = [-1,0]

Can't try for a few days what's the result?

Very complicated, but I used it in my S-Unit 2.0. It works quite well.

Code: Select all

{math.asin(e.normal(0)) > 0} ? {controllerAcc = math.acos(e.normal(0))} : {controllerAcc = (-1) * (math.acos(e.normal(1)))}

Should work (typed from memory), and stores the angle in controllerAcc. 0 is up (talking about normals here), clockwise is positive, counterclockwise is negative. Exactly ideal for air-friction stabilizers.

the result will be a undefined result because of dividing by zero^^

I just tested it. Strangely enough, I've been using that method for 6 months perhaps and never come across any issues with it.

The only problem I can see with my code is that when the normal points down, it may give [math.pi] or [- math.pi]. But that should be easy to get around.
