How to jump higher when you hold down with *touch* controls
So I looked through similar questions here on how to jump higher when a button is pressed but since my game is for mobile I need to make it based on when the user taps on the screen and holds it down for a certain period of time.
Here's what I have:
void Update () {
// Reset total jumps allowed when not performing a jump and grounded or when on a moving platform.
if (!jump && (player.grounded || player.IsStuckToPlatform())) {
jumps = doubleJumping.totalJumps;
}
//physical button jump
if (Input.GetButtonDown("Jump")){ //add touch to hold down here?
StartJump();
}
//tap jump
int nbTouches = Input.touchCount;
if(nbTouches > 0)
StartJump();
}
Void StartJump has the code for the jumping but the actual jumping based on how long a button was pressed is in fixedupdate. If I hold down up or spacebar my character does jump higher but when I tap on the screen the jump is the lowest jump possible as it doesn't detect that I'm constantly holding it down for a higher jump.
Edit: I think I know whats happening, its detecting my touch as a mouse click but doesn't detect when I hold it longer as I would a button. I can't find anything regarding holding down the touchscreen. OnMouseButtonDown doesn't work as it for some weird reason gives me an error.
You need to examine the touchPhase of each touch on the screen: http://docs.unity3d.com/ScriptReference/TouchPhase.html
In the frame in which the touch is first registered, this will be "Began". In every subsequent frame the touch is held, it will either be "Stationary " or "Moved", until it is ended or cancelled. So you can consider those two states as equivalent to a mouse or key button being held.
I tried that but I can't wrap my head around how I'm suppose to put it in this code. This isn't code I wrote btw, I'm trying to build on top of it and make mobile touch controls.
This is what I have in update:
//physical button jump
if (Input.GetButtonDown("Jump")){ //add touch to hold down here?
StartJump();
}
if (Input.GetTouch(0).phase == TouchPhase.Began){
StartJump();
}
This is Fixed Update which runs how high the player goes based on how long the button was pressed:
// If you need to hold the Jump input to jump higher...
if (jumpType == JumpType.HoldToJumpHigher) {
// When there is an initial jump...
if (initialJump) {
// ... set the y velocity to the player's initial jump value.
float yVel = jumpFactor * (doubleJump ? holdToJumpHigher.initialDoubleJump : holdToJumpHigher.initialJump);
And this is the start jump function:
void StartJump(){
// If the jump button is pressed, jumps are allowed and the player is not dashing, sliding, on a ladder or crouching under an obstacle...
if (!jump && jumps > 0 && !player.dashing && !player.sliding && !player.onLadder && (!player.crouching || (player.crouching && player.AllowedToStandUp()))) {
// If the player is grounded...
if (player.grounded) {
// ... initialize jump.
InitJump();
// If the player is not grounded and totalJumps is higher than 1...
} else if(doubleJumping.totalJumps > 1) {
// ... initialize jump if the Y velocity is inside the double jump window (or when there isn't a window).
if (!doubleJumping.jumpWindow || (doubleJumping.jumpWindow && rigidbody2D.velocity.y > doubleJumping.jumpWindowMin && rigidbody2D.velocity.y < doubleJumping.jumpWindowMax)) {
doubleJump = true;
InitJump();
}
}
}
}
I think what I have to do is figure out how to make the fixedupdate function into its own seperate function then in update call "if touchphase.stationary call holdtojumphigher();"
Problem is that the variable created in that fixedupdate is used in the rest of fixed update.
