   Hey Developers,

   I hope you will answer to my question this time… I got a problem : Here is my code : (character is a CCSprite)

   -(void) tick: (ccTime) dt
   {
   		NSLog(@"selected");
   		character.position.x += 1;
   }

   I don't know why, but an error occures when I build the project : "Lvalue requiered as left operand of assignment"

   Any ideas to resolve this problem ?

   Thanks in advance,
   Best regards

   Hi I just wrote a question a few down from this at http://www.cocos2d-iphone.org/forum/topic/8207 dealing with this. You can't increment position like you did there, you have to ccp(character.position.x+1, character.position.y). I was hoping riq might have some ideas around this.

   Thanks for your answer, but I found this :

   id actionMove = [CCMoveBy actionWithDuration:0.0 position:ccp(-1, 0)];
    [character runAction:actionMove];

   I found this a couple hours ago ;)

   You don't need to use the action if you don't want to, like @michaelm said you just needed to include the Y portion of your position update like so:

   -(void) tick: (ccTime) dt
   {
   		NSLog(@"selected");
   		character.position = ccp(character.position.x + 1, character.position.y);
   }
