Physics2D.BoxCast questions

Hi all,

I'm trying to use the Physics2D.BoxCast function to check for a collision. I'm sure there I'm missing something because it only works if the left edge of the box casted collides with the right edge of the target collider. This is the function:

Code (CSharp):

1. RaycastHit2D hit = Physics2D.BoxCast(
2.             this.boxCollider.bounds.center,
3.             this.boxCollider.size,
4.             0,
5.             Vector2.left,
6.             0.1f,
7.             this.target
8.         );

The target is the layermask of an object with boxcollider2d. The collider is just a collider I assigned from the editor.

Another thing, if I put 0 instead of 0.1f in the distance there is no collision at all. Any help with this please? What I want to achieve is check if the casted box collides with another collider, at any point, I mean, even if they are overlapping. Sure this is a very newbie mistake but I'm a newbie

 

You're in luck: this question sounds like it is right up @MelvMay 's alley!

 

You probably want to use OverlapBox instead of BoxCast with distance 0.

 

Thank you guys OverlapBox works perfectly!

I don't really know much about this, I'm just trying to follow the examples I see and then adapt them to my needs I'm using colliders with the OnTriggerEvent2D for other things but in this case is an enemy with his collider for the body and another one in front for the attack so when the player touches the attack collider I trigger the attack animation, bt the attack has some delay and the damage is triggered in a certain point during the animation so I need to let the player keep inside the collider and then check for overlap again when the animation triggers the damage function.

Even if I use the OnTriggerEvent2D for starting the animation I need a way to check later if the player is still overlaping the collider or has dodge the attack. Is another better way of doing this?

Edit: the first thing that comes to my mind is having an Attack flag and set it to true when the animation frame triggers the event, but I don't know if that's more effective... thoughts?
