Using both RB Velocity and AddForce?
Hello, I am working on a 2D platformer and i use Rigidbody2D.velocity to move. It is easier to stop the player if i am not pressing a key and removes acceleration. But i wanted to push the player back when there is a collision with an enemy and because the velocity is set to 0 when no key is pressed, i can't use "AddForce", the player stops in air. So i was wondering if there is a solution to keep make the player stop instantly but keep the AddForce.
Here is my code :
void Movement()
{
//Move
float horizontal = Input.GetAxis("Horizontal");
rb2D.velocity = new Vector2(horizontal * speed, rb2D.velocity.y);
//Jump
rb2D.AddForce(new Vector2(0, jumpForce), ForceMode.Impulse);
//Getting pushed back by enemy (debug)
if(Input.GetKeyDown(KeyCode.T))
rb2D.AddForce(new Vector2(-pushForce, 0)ForceMode.Impulse);
}
Good day.
IF velocity = 0 is applied, the addforce will have no effect.
So you need to dont apply the velocity command during the time you want it to move back.
This is probably a bit late, but to fix this you can make the player be unable to move for like one third of a second when getting knocked back.
void Movement()
{
//Move
float horizontal = Input.GetAxis("Horizontal");
if (beingknocked == true)
rb2D.velocity = new Vector2(horizontal * speed, rb2D.velocity.y);
//Jump
if (beingknocked == false)
rb2D.AddForce(new Vector2(0, jumpForce), ForceMode.Impulse);
//Getting pushed back by enemy (debug)
if(Input.GetKeyDown(KeyCode.T))
rb2D.AddForce(new Vector2(-pushForce, 0)ForceMode.Impulse);
beingknocked = true
yield return new WaitForSeconds(0.3);
beingknocked = false
}
This way the player gets stunned when knocked back so the rb.velocity command won't interfere with the addforce.
