Tag: scripts

The script is attached to a Camera. A bit messed but it’s working.

For changing the camera height at run time I’m using a variable name cameraHeight at this line number 88:

Vector3 negDistance = new Vector3(0.0f, cameraHeight, -distanceFromTarget);

The original line was :

Vector3 negDistance = new Vector3(0.0f, 0.0f, -distanceFromTarget);

but if instead, I want to create a public method something like :

public void ChangeCameraAngle()
{

}

What should I do inside this method and then how to use it for things like changing the camera(transform) height or angle in run time?
