Functions​

AddExplosionForce​

void AddExplosionForce (float explosionForce, SVector explosionPosition, float explosionRadius, float upwardsModifier)

Applies a force to a rigidbody that simulates explosion effects. Other rigidbodies will be affected by the explosion within its radius - the closer they are to the explosionPosition, the stronger the force will be exerted on them.

ParameterTypeDescription
Space.Host.ExecutingObject.Rigidbody.AddExplosionForce (300, Vector.New(0,0,0), 10, 20)
local obj = Space.Host.ExecutingObject;

obj.Rigidbody.AddExplosionForce (300, obj.WorldPosition, 10, 20)
-- The explosion will occur at the location of the ExecutingObject.
-- Place other rigidbodies around it to observe the effect!

AddForce​

Adds a force to the Rigidbody that is continuously exerted on it in the given direction.

ParameterTypeDescription
Space.Host.ExecutingObject.Rigidbody.AddForce(Vector.New(0,1,0))
local obj = Space.Host.ExecutingObject;

-- Now the rigidbody is under a continuous force directed upwards (Y direction)

AddForceAtPosition​
