DROPDOWN QUESTION

Based on the API definition, select the correct implementation of the AddForce() function from the dropdown menu.

Rigidbody.AddForce

public void AddForce(float x, float y, float z, ForceMode mode = ForceMode.Force);

Parameters:

∎x Size of force along the world x-axis.

∎y Size of force along the world y-axis.

∎z Size of force along the world z-axis.

∎mode Type of force to apply.

Description:

Adds a force to the Rigidbody.

Force is applied continuously along the direction of the x,y, and z vectors. Specifying the ForceMode mode allows the type of force to be changed to an Acceleration, Impuls, or Velocity Change.

Force can be applied only to an active Rigidbody. If a GameObject is inactive, AddForce has no effect.

By default, the Rigidbody's state is set to awake once a force is applied unless the force is Vector3.zero.​ ​ (a)  

Choose One...
AddForce(0, 0, thrust, ForceMode.Impulse);
AddForce("0", "0", thrust, ForceMode.Impulse);
AddForce(0, 0, ForceMode.Impulse);
