My current script has lots of issues like if you hold down the left click it will just follow the mouse, and the cooldown won't occur. When the player moves within range of an enemy, the enemy should start following the player. Force can be applied only to an active rigidbody. Specifying the ForceMode mode allows the type of force to be changed to an Acceleration, Impulse or Velocity Change. Force is applied continuously along the direction of the force vector. The force must be applied only on the XZ plane, so no need to calculate Y height. Force can be applied only to an active rigidbody. For example, a force using new Vector2 (4, 5) will apply a force of 4 units horizontally right and 5 units vertically upwards. If the force size is zero then the Rigidbody will not be woken up. Adding a force is one way to do it. forward * 100); These are all pretty self-explanatory. The default in this case is ForceMode2D.Force which adds force over time, using mass. rotationDirection) as GameObject; newRocket.rigidbody.AddForce ((target.transform.position - transform.position).normalized * projectileSpeed); . So that the rocket is fired from the spawnPoint with a rotation/direction that means it will go towards and through the cross hair. I got the vector direction by subtracting the two positions and debugged it successfully. { // Move the object forward along its z axis 1. Vector3 moveAmount = transform. I've looked around and lots of people are saying to use transform.LookAt and then rigidbody.AddForce (transform.forward) How could I achieve this effect without using LookAt. On iOS, I have a wrecked car with a Rigidoby that should be pushed towards a specified target in the space (that target is the position where you touch the screen).
