Double Jump Help
Hello Unity Community,
I Am A Sort - Of Newb At Unity, And I Need Scripting Help. I Need That When The Y Position Of My Camera Is Less Than The Position Of An Induvidual Waterplane, My Character Can "Swim", By Infinite Jumping, But When The Camera Is At Or Above The Waterplane's Y, I Can Only Do One Jump. Here Is My Script:

Hi TCE,
You can try to detect how often you jumped in your:
if (m_Jump)
{
m_MoveDir.y = m_JumpSpeed;
PlayJumpSound();
m_Jump = false;
m_Jumping = true;
}
method. Just add these variables on top:
[SerializeField] private int m_MaxJumpCount = 2; // in case you want an tripple jump
private int m_JumpCount = 0;
edit your if(m_Jump) to:
if (m_Jump)
{
m_JumpCount++; // add one to jump count
m_MoveDir.y = m_JumpSpeed;
PlayJumpSound();
m_Jump = false;
m_Jumping = true;
}
than just add this after your if(m_jump) method:
if (m_Jumping)
{
if(m_JumpCount < m_MaxJumpCount) // stop double jumping if max reached
{
if (m_Jump)
{
m_JumpCount++; // add one to jumping
m_Jump = false;
}
m_MoveDir.y += m_JumpSpeed;
PlayJumpSound();
m_Jump = false;
m_Jumping = true;
}
}
else // if not jumping reset jump count
{
m_JumpCount = 0;
}
Hope this will work for you.
@JScotty Thanks A Lot, But Lets Say I Want The Mex Jumps Variable To Be Infinite, But Only If The Camera Is Under The Y Level Of A Waterplane, Or Else The Max Jumps Variable Is Equal To One. Will It Work Like This?
public class ExampleThing : MonoBehavior {
public int maxjumps = 1; public GameObject[] water;
void Start(){
water = GameObject.FindGameObjectsWithTag("Water");
}
if(this.transform.position.y < water.transform.position.y){
maxjumps = infinity;
}
if(this.transform.position.y >= water.transform.position.y){
maxjumps = 1;
}
}
thanks,

Yes you can use checking if whater is above you, or you create an collider under water and use OnTriggerEnter/OnTriggerStay to check if you are under water, and use OnTriggerExit when you leaving water.
For this you can indeed use a boolean m_IsInWater = true and then edit your if(m_Jump) to:
if (m_Jump)
{
if(m_IsInWater) // jump infinity
{
m_$$anonymous$$oveDir.y = m_JumpSpeed;
PlayJumpSound();
m_Jump = false;
}
else
{
m_JumpCount++; // add one to jump count
m_$$anonymous$$oveDir.y = m_JumpSpeed;
m_Jump = false;
m_Jumping = true;
PlayJumpSound();
}
}
