Increase variable for a few seconds
Hi,
I want to increase the speed of my character by 5 (in this example) when I collide with my power up and then return back to normal after a set time.
Now, this works but as I want it to.
The way it works now is... I collide, speed goes up but the game object is still there. It is only deleted once the yield is finished. I heard I cannot delete the object until the process is over other it doesn't work.
Its not really a power up if it isn't removed from the scene.
To get around this, I removed the Sprite Rendered. The object becomes invisible which works I guess. But now, during the process, if i touch this invisible object, the speed increase as many times as I touch it till it is deleted...
Here is my code:
void OnCollisionEnter2D(Collision2D other)
{
if (other.gameObject.tag == "Player")
{
PlayerMovement.movespeed += 5;
StartCoroutine(speedTime());
GetComponent<SpriteRenderer>().enabled = false;
}
}
IEnumerator speedTime ()
{
yield return new WaitForSeconds(3);
revertSpeed();
Destroy(gameObject);
}
void revertSpeed ()
{
PlayerMovement.movespeed = 2;
}
What is the best way to get around this?
Thanks
Can you try on line 3:
if (other.gameObject.tag == "Player" && gameObject.transform enabled = true)
That way you only receive the power-up if the object is visible. Not exactly destroyed but close enough.
Sorry if my syntax is bad, hope you get the idea.
I guess if you just remove any visual and physical interaction, you can keep your object there until destruction
void OnCollisionEnter2D(Collision2D other)
{
if (other.gameObject.tag == "Player")
{
renderer.enabled = false; // Remove visual
collider.enabled = false; // Remove physical
PlayerMovement.movespeed += 5;
StartCoroutine(speedTime());
GetComponent<SpriteRenderer>().enabled = false;
}
}
I didn't know I can remove colliders like that. This definitely helped. Thanks a lot
the easiest way I can think of is to have a bool variable that is off initially and then turned on after collision, it works for what you want and you can reenable it for respawning power-ups.
private bool tripped = false;
void OnCollisionEnter2D(Collision2D other)
{
if (other.gameObject.tag == "Player" && !tripped)
{
tripped = true; // this stops OnCollisionEn.... from running again
PlayerMovement.movespeed += 5;
StartCoroutine(speedTime());
GetComponent<SpriteRenderer>().enabled = false;
}
}
IEnumerator speedTime ()
{
yield return new WaitForSeconds(3);
revertSpeed();
Destroy(gameObject);
}
void revertSpeed ()
{
PlayerMovement.movespeed = 2;
}`
But the collider is still on so your guy is about to bump on it. Actually he should use Trigger.
