Swapping player's controls in game (2D)
I have an object, which when triggered by the player has to swap the selected player's left and right controls. The controls: 
using UnityEngine;
using System.Collections;
using character;
using UnityStandardAssets.CrossPlatformInput;
public class confuse_powerup : MonoBehaviour {
void OnTriggerEnter2D(Collider2D other)
{
if (other.gameObject.name == "player1")
{
// SWAP LEFT,RIGHT CONTROLS
}
else if (other.gameObject.name == "player2")
{
// SWAP LEFT,RIGHT CONTROLS
}
}
}
I tried swapping the keys but it didnt work :
var left = Input.GetKey("a");
var right = Input.GetKey("d");
left = Input.GetKey("d");
right = Input.GetKey("a");
I think you're approaching this the wrong way... you don't need to remap the key input to reverse the direction when you pick up that powerup - you simply modify the way that the input is applied to the character controller.
We can't see your code for that bit, but you probably have something like:
transform.position += new Vector3(horizontalInput, verticalInput, 0);
So what you need to do is modify the horizontal input depending on whether the player is confused or not, like:
horiozontalInput *= isConfused ? -1 : 1;
transform.position += new Vector3(horizontalInput, verticalInput, 0);
And you use your OnTriggerEnter to set the isConfused bool.
