Trying to make some dashing code, however it crashes if it's not coroutine.

Questions & Answers
1

so i made this chunk of code

IEnumerator dash()
{
    float startTime = Time.time;
    while (Time.time < startTime + dashingTime)
    {
        controller.Move(transform.right * dashingPower * Time.deltaTime);

        yield return null;
    }
}

which is fine but i don’t want this to repeat so try to make in not a coroutine so i just make it a method like this

void dash()
{
    float startTime = Time.time;
    while (Time.time < startTime + dashingTime)
    {
        controller.Move(transform.right * dashingPower * Time.deltaTime);
    }
}

this for reasons i can not explain completely nukes unity. does anyone have an answer for what i’m doing wrong, what is happening it runs fine as a coroutine but it doesn’t do what i want.

Hello.

You need to understand how IEnumerator works. I will try to explain the basic, the usefull info between IEnumerators and Void functions

IEnumerators are like void functions, they do not repeat themselves (they are usefull for repeating, but you have to command that repeating, they do not repeat automaticly), they are coroutines because they can be “delayed” over time, but they are not automatic in any kind, they are the same as void functions.

The only difference is that you can place yield commands.

This yields allow the function to stop running durint some time/frames, so other part of the code can run while is waiting.

This means, that a while inside a void function will be looping forever until the condition is not true, and no other code will run, so, the computer will be doing that while and only that while. This means the cimputer “freezes” until execution go outside the while.

But, in a Ienumerator, if you use a while and place a yield command inside the while , the computer will run the other scripts during yield, so the game will not “freeze”, only that function will be freezed.
