Question by dogi257 · Aug 31, 2019 at 10:33 PM · 2d2d game2d-physics

2D random shooting problem with velocity,

Hello,

I wrote this simple line of code which should make it so that the bullet has a random shot direction, it works but the problem is that the bullet also has a random speed... Is there any way to set it up so that the bullet has a set speed (like a variable), but it still shoots in a random direction?

Thank you for your answers :D

The code is -

bul.GetComponent().velocity = new Vector2 (Randomnum2, Randomnum) * bulletSpeed;

to have the same magnitude (1 probably) you can just randomize the angle,

 float angle = Random.Range(0f, 2*$$anonymous$$athf.PI);
 bul.GetComponent().velocity($$anonymous$$athf.Cos(angle), $$anonymous$$athf.Sin(angle));

or, in the other hand, normalize the generated vector:

 bul.GetComponent().velocity = (new Vector2 (Randomnum2, Randomnum)).normalized * bulletSpeed;
