2D Limit player speed
Hello I am working on a endless runner.I am using InvokeRepeating for adding speed to my player but I have problem with it.I want to limit my max player speed to 20f. How can I do this?
Assuming you want limit the speed on the x axis
public float maxVelocity = 20f;
//put this inside your invoke repeating
if(rb.velocity.x > maxVelocity)
{
rb.velocity = new Vector2(maxVelocity, rb.velocity.y);
}
Hi bud.
If you are using rigidbody to move use:
Rigidbody2D = rb;
public float maxVelocity = 20f
void FixedUpdate()
{
if(rb.velocity > maxVelocity)
{
rb.velocity = maxVelocity
}
}
Hope that solves your problem.
If you are using any other way of moving, feel free to let me know. i'll help you.
it gives a error that says cannot implicitly convert type 'float' to 'UnityEngine.Vector2'
Rigidbody = rb;
public float maxVelocity = 20.0f
void FixedUpdate()
{
if (rb.velocity >= maxVelocity)
{
rb.velocity = maxVelocity;
}
}
If the player is moving up the screen use:
maxVelocity = 20f;
if (rb.velocity.magnitude > maxVelocity) {
rb.velocity = Vector2.up * maxVelocity;
}
If they're moving left to right use:
maxVelocity = 20f;
if (rb.velocity.magnitude > maxVelocity) {
rb.velocity = Vector2.right * maxVelocity;
}
To increase performance, you can replace the (rb.velocity.magnitude > maxVelocity) with (rb.velocity.sqrMagnitude > Mathf.Pow(maxVelocity, 2))
If this works please mark the question answered. If it doesn't please ask any questions I'm happy to help :)
it gives a error that says Invalid token '=' in class, struct, or interface member declaration.If I change maxVelocity to int or float still doesnt work. I think it happens cuz I am using velocity and float in the same code.Is there any way to limit float without velocity?
sry for bad English :)
Sorry I made a mistake when typing that. In the if statement it should say: if (rb.velocity.magnitude > maxVelocity)
A cheaper option is to use if (rb.velocity.sqr$$anonymous$$agnitude > $$anonymous$$athf.Pow(maxVelocity, 2))
As I am not in the unity editor right now, I'm not certain of the capitalisation and things like that, but if you use the autocorrect to find the right function either of those should work.
EDIT: I have updated my original answer now so you can just refer to that
