[Resolvido] oque esta errado nessa funçao?

var newplayerX = 10;
var newplayerY = 10;
function drawMap(){

	for(i=0;i<map.length;i++){
 for(j=0;j<map[i].length;j++){
 var drawTile= map[i][j];
 var drawObj = objectMap[i][j];
 var xpos = (i-j)*tileH + mapX;
 var ypos = (i+j)*tileH/2+ mapY;
 ctx.drawImage(tileImg[drawTile],xpos,ypos);
 if(drawObj){
 ctx.drawImage(objectImg[drawObj-1],xpos,ypos-(objectImg[drawObj-1].height/2));
 }

 }

	}

function addplayer()

{

var xpos = (newplayerX+newplayerY)*tileH + mapX;
var ypos = (newplayerX+newplayerY)*tileH/2+ mapY;
ctx.drawImage(charImg[0],xpos,ypos-(charImg[0].height/2));

}

porque nao funciona a funçao addplayer?

alguem sabe como resolver?
