Check if the player is on the ground. Unity4.3 (2D)

[Dunkelheit]

I’m checking the new 2D features in Unity 4.3 edition. So they changed some components to work now with 2D environment. I’m using Physics2D.Linecast to check if player is on the ground. But everywhere my char stay on ground, even if it’s jumping. My ground is marked as ground to get correct layer to compare char vector with the ground’s one.

grounded = Physics2D.Linecast(transform.position, groundCheck.position, 1 << LayerMask.NameToLayer("Ground"));

• “grounded” is a bool to check if player is on the ground;
• “transform” refers player’s transform;
• “groundCheck” is an emptyObject put into player to mark ground directions.

Since I’m using the new resources, probably raycast or “old” components to handle 3D environments can’t help me there.

Thanks in advance and sorry about my english.

You need to use Vector2 as arguments for the Physics2D.Linecast. I made the same mistake when migrating to 2D physics Something like

var MyPos : Vector2 = Vector2(transform.position.x, transform.position.y);
var GroundCheckPos : Vector2 = Vector2(groundCheck.position.x, groundCheck.position.y);
Physics2D.Linecast(MyPos , GroundCheckPos , 1 << LayerMask.NameToLayer("Ground"));
