Drop through platform script
I am trying to make a script to drop through certain platforms. I have got it to almost work using collider2d.enabled = false; The problem is it only turns off one of the colliders on my character and I need it to turn off 2 colliders. Is there a way to specify which collider it should turn off? Here is the code for it so far
//platform fallthrough script
if (allowPlatformDropThrough) {
foreach (Transform groundCheck in groundChecks) {
RaycastHit2D fallThrough = Physics2D.Linecast (transform.position, groundCheck.position, 1 << LayerMask.NameToLayer ("fallThrough"));
if (grounded && fallThrough && Input.GetAxis ("Vertical") < 0) {
//rigidbody2D.collisionDetectionMode = false;
collider2D.enabled = false;
}
if (!fallThrough) {
collider2D.enabled = true;
}
}
}
About using more than one collider see here: http://answers.unity3d.com/questions/188775/having-more-than-one-collider-in-a-gameobject.html
Why do you need more than one collider?
the character has a box collider for their body and a circle collider for their feet. This is all done in 2d so the characters feet don't get caught on tiny edges.
You can just disable all the colliders at once.
var colliders = GetComponents<Collider2D>();
foreach (var col in colliders)
{
collider.enabled = false;
}
You can also check whether the collider isTrigger inside loop to avoid turning off triggers or check col is BoxCollider2D for instance to check if it is a collider of specific type.
I'm very new to scripting so all of that code was just a guess. I tried to add the bit you suggested but it still only seems to turn off the first collider in the inspector list. I added public Collider2D[] col; to the variables and attached each collider2d and modified the code to the following
//platform fallthrough script
if (allowPlatformDropThrough) {
foreach (Transform groundCheck in groundChecks) {
RaycastHit2D fallThrough = Physics2D.Linecast (transform.position, groundCheck.position, 1 << Layer$$anonymous$$ask.NameToLayer ("fallThrough"));
if (grounded && fallThrough && Input.GetAxis ("Vertical") < 0) {
var colliders = GetComponents<Collider2D>();
foreach (var col in colliders)
{
collider2D.enabled = false;
}
}
if (!fallThrough) {
collider2D.enabled = true;
}
}
}
I could add the full character controller code if you think it would help. It's a mess though.
Does anyone have an idea of how to disable all the colliders on a gameObject?
