Well I’m an Amateur in AS2 coding so Here is the code i use for walking,

on(keyPress “\<Up\>”)  
{ this.\_y -= 5;  
this.gotoAndStop(2)}  
on(keyPress “\<Left\>”)  
{ this.\_x -= 5;  
this.gotoAndStop(3)}  
on(keyPress “\<Right\>”)  
{ this.\_x += 5;  
this.gotoAndStop(4)}  
on(keyPress “\<Down\>”)  
{ this.\_y += 5;  
this.gotoAndStop(1)}

How would I make it so when My mc hits a wall it stops or bounces off?:ub:
