Moving a Platform
Hello,
I was wondering if I could have some help with creating a moving platform. I am relatively new to programming so bare with me.
Basically I want a platform's y value to continually change.
The following code is what i have so far. The problem I am currently having is that the two subroutines are running at the same time, I don't know why that is. Any help is much appreciated.
Thanks
function Start () {
}
function Update() {
StartCoroutine("eleup");
StartCoroutine("eledown");
}
function eleup(){ // Move up to y = 20
while (transform.position.y < 20){
transform.position += Vector3.up * Time.deltaTime*5;
yield WaitForSeconds(.5);
}
}
function eledown(){ //move down to 0
while (transform.position.y > 0){
transform.position += Vector3.down * Time.deltaTime*5;
yield WaitForSeconds(.5);
}
}
By calling eleup and eledown with StartCoroutine you're basically starting them both at "the same time" and letting them run independently. The problem only gets worse since you're starting more coroutines each update.
A possible solution would be just to handle the position updating straight in Update:
var elevatorDirection : Vector3 = Vector3.up;
function Update(){
transform.position += elevatorDirection * Time.deltaTime * 5;
if(transform.position.y < 0) {
elevatorDirection = Vector3.up;
}
if(transform.position.y > 20) {
elevatorDirection = Vector3.down;
}
}
Thank you very much for your help, worked perfectly. I hope I didn't make myself look like to much of an idiot. I thought that the way I had it set up it would run the first coroutine and then, once its done, run the second. Thanks again for your help.

Heh, don't worry. Software development is a lifelong pursuit of perfection. :D
