Mixing these means anytime you edit the Transform, you're ripping the object out of the control of the physics engine, teleporting it, then throwing it back in haphazardly. If you want your object to move with physics, let the physics engine handle all its movement. You should not mix Transform changes (like transform.Translate()) with Rigidbody/ Rigidbody2D movement. Rb.velocity = direction * Mathf.Max(speed, 2f) īut when I use this code, they don't bounce off the wall. Var direction = Vector3.Reflect(lastVelocity.normalized, ) Void OnCollisionEnter2D(Collision2D collision) Transform.Translate(Vector3.down * DropSpeed * ltaTime)

= Vector2.one * spawnSize Īnd then I use this script to move them down along their local 'down' vector (which may be pointing along a diagonal), and reflect them off of the walls when they hit: float DropSpeed = 10f GameObject newBlock = (GameObject)Instantiate(fallingRock, SpawnPos, Quaternion.Euler(Vector3.forward * spawnAngle))

I hope you found this blog helpful while working Fire Bullet with Trail Effect in Unity.

Public GameObject gun, bulletPosition, bulletPrefeb, shotIcon Icon will appear on touch down and to denote target of bullet Position of bullet from where bullet will be fired. Move according to touch, this object can be replaced as per game requirement. Create an empty gameobject and attach this script to it. This script will illustrate a gun firing a bullet according to touch position.
