This function calculates and adds a force to move the entity to the specified position in one physics step.

Syntax

• void PhysicsSetPosition(const float x, const float y, const float z, const float strength=0.5)
• void PhysicsSetPosition(const Vec3& position, const float strength=0.5)

Parameters

• x: the X component of the position to move to.
• y: the Y component of the position to move to.
• z: the Z component of the position to move to.
• strength: a multiplier to determine how strong the force to move the entity should be. If the strength is too low, the movement will be laggy. If the strength is too high, a rubber banding effect will be apparent.
