MonoBehaviour.OnCollisionStay2D(Collision2D)

Description

Sent each frame where a collider on another object is touching this object's collider (2D physics only).

Further information about the objects involved is reported in the Collision2D parameter passed during the call. If you don't need this information then you can declare OnCollisionStay2D without the parameter.

var rechargeRate = 10.0;
var batteryLevel: float;
function OnCollisionStay2D(coll: Collision2D) {
	if (coll.gameObject.tag == "RechargePoint")
		batteryLevel = Mathf.Min(batteryLevel + rechargeRate * Time.deltaTime, 100.0);
}

            batteryLevel = Mathf.Min(batteryLevel + rechargeRate * Time.deltaTime, 100.0F);
