How to shoot raycast with slight random direction?
I want to shoot a raycast to check where my gun has fired, but with the shotgun I'm going to want to randomize the precise direction of the ray slightly with each shot.
How would I do this?
Currently I use if (Physics.Raycast(shotOrigin.position, shotOrigin.forward, out hit, 1000, layerMask)) to shoot a ray straight out (forward) from the barrel of the gun with each shot, so I need to find a way to vary that "forward" angle up a little bit.
You might want to use Quaternion.AngleAxis. Create a random float for your angle and multiply shotOrigin.Forward by the value you will get from AngleAxis value
Can you show me how this would look in code with an example, because I'm not sure what you mean (as in how to write it correctly)?
Here's my code as it exists right now:
private void RaycastGun()
{
int numberOfBullets = 1;
if (WeaponSelectionController.weaponNumberRightHand == 2) // The Shotgun
{
numberOfBullets = 15;
}
int layer$$anonymous$$ask = ((1 << 10) | (1 << 11) | (1 << 13));
layer$$anonymous$$ask = ~layer$$anonymous$$ask;
RaycastHit hit;
for (int i = 0; i < numberOfBullets; i++)
{
if (Physics.Raycast(shotOrigin.position, shotOrigin.forward, out hit, 1000, layer$$anonymous$$ask))
{
GameObject theObject = hit.collider.gameObject;
if (hit.collider.gameObject.CompareTag("Enemy"))
{
// Do stuff
}
}
}
}
Something like this:
float randomAngle = new System.Random($$anonymous$$Angle, maxAngle);
Vector3 axis = new Vector3(1, 1, 0);
var rotation = Quaternion.AngleAxis(randomAngle, axis);
if (Physics.Raycast(shotOrigin.position, rotation * shotOrigin.forward, out hit, 1000, layer$$anonymous$$ask))
I'm only not sure if I'm using the correct axis, so if you get weird results you might want to tinker with that first.
Cool.
I'll give it a go and see what happens. . . .
