The player is moving, and if they collide with trigger A, they will stop moving for 1 second, and then start moving. If the player collides with trigger B, they will stop moving for 2 seconds. However, the speeds get mixed up if the player collides with A and then quickly collides with B, so the player will start moving even though they should be still.
It’s difficult to explain, basically if player collides with A, then collides with B straight after, I would like the effect of A to be cancelled, and the effect of B to start. Here is the code for them
if (col.gameObject.tag == "trigA")
{
speed = 0f;
yield return new WaitForSeconds(1);
speed = 21f;
}
if (col.gameObject.tag == "trigB")
{
speed = 0f;
yield return new WaitForSeconds(2);
speed = 21f;
}
“Hello guys” probably won’t get you a quicker answer in the future.
You need add another statement to your IF’s. What the new If statement is saying is that if trigA is true and trigB is not true then proceed with the if statement, but if trigB becomes true then the statement will become false so your IF with trigB alone should take priority.
if (col.gameObject.tag == "trigA" && col.gameObject.tag != "trigB")
{
5. speed = 0f;
yield return new WaitForSeconds(1);
speed = 21f;
}
10.
if (col.gameObject.tag == "trigB")
{
speed = 0f;
15. yield return new WaitForSeconds(2);
speed = 21f;
}
}
It’s obvious why because of the way you have written the code, the situation will occur if the player hits both triggers together. The yield functions allow both triggers to run on a double hit.
Sequence on a double hit
trigA sets the speed to zero then yields
trigB sets the speed to zero (the yield of trigA allows another entry)
trigA comes back from yielding and sets speed to 21. <==== WRONG
trigB comes back from yielding and sets speed to 21 but player is already moving
The triggers are both hit … yielding will allow two calls on top of each other … that is the error
Welcome to multitask programming
Two simple solutions
write a non yielding delay
use private bools and track the trigger states
Option 2 looks like this
// place these at top of class
private bool trigA = false;
private bool trigB = false;</code>
</pre>
<pre>`// now fix your code sample
if (col.gameObject.tag == "trigA") {
trigA = true; // set trigA bool
speed = 0f;
yield return new WaitForSeconds(1);
trigA = false; // clear trigA bool
if (!trigB) speed = 21f; // if trigB isn't active release
}
if (col.gameObject.tag == "trigB") {
trigB = true; // set trigB bool
speed = 0f;
yield return new WaitForSeconds(2);
trigB = false; // release trig B bool
if (!trigA) speed = 21f; // if trigA isn't active release
}
