Have a function to Wait until true?
Hi there,
I have a spawn function thats called every time my player dies. It basically turns off all the colliders and renderers on my player, moves it to a 'spawn point' wait a few seconds, and turns the player back on.
Is it possible to have this function to wait until a certain external variable is true, and then carry on?
So, right now it does:
Turn off player
Move player
Wait a few seconds
Turn player on
I now want it to do:
Turn off player
Move player
Wait until 'blah' is true
Turn player on
If your wondering... that 'Blah' is a weapon list that pops up when you die, and when the player selects the weapon he wants, 'blah' comes true. Thus then continuing to spawn the player.
I know theres all sorts of different methods. But I really want to know if a form of 'yield' is possible?
Thanks
I figured it out, not as complicated as I thought:
function Spawn(){
turnOffPlayer();
while(weaponSelected == false){
yield;
}
turnOnPlayer();
}
See the manual on coroutines.
IEnumerator Spawn() {
turnOffPlayer();
while(weaponSelected == false){
yield return null;
}
turnOnPlayer();
}
Without the while loop in C# using WaitUntil
IEnumerator Spawn() {
turnOffPlayer();
yield return new WaitUntil(() => weaponSelected == true);
turnOnPlayer();
}
using lambada ........ GENIAL, why i don't get it myself and googling like idiot ?
Why would you make it understandable while you can use some obscure lambda expression?
To remove the lambda, you can put it in a normal function:
bool HasSelection() {
return weaponSelected;
}
IEnumerator Spawn() {
turnOffPlayer();
yield return new WaitUntil(HasSelection);
turnOnPlayer();
}
This is....amazing. Thank you. This is probably the easiest method ive seen so far.
Time_Flys example: Don't forget to use
StartCoroutine(Spawn());
Otherwise it would not work.
Correct me if im wrong, but isnt it
StartCoroutine("Spawn");
Using async/await via https://assetstore.unity.com/packages/tools/integration/async-await-support-101056
async void Spawn() {
turnOffPlayer();
await new WaitUntil(() => weaponSelected == true);
turnOnPlayer();
}
Note: I love the async/await paradigm (having used it in javascript/typescript) but I only recently started using it C# Unity so I'm not sure of any side-effects but haven't come across any so far. Makes the code soooo much cleaner IMHO.
await new WaitUntil(() => weaponSelected == true); This version waits per frame until weaponSelected == true. This is already asynchronous!
async void Spawn() .. Could you explain this, please.
