Question

I have a function called collisioncheck. Right now it works perfectly by checking variables that apply to a player, such as playerPosX, playerVelX, playermaskIMG, etc.

What I want to do is something like collisioncheck(object), so that say I call collisioncheck(player) it will check the variables like above with playerPosX etc. and if I call collisioncheck(zombie) then it will instead check zombiePosX, etc.

How could I do this?

If you have any questions please ask as I am not really very good at explaining this…
thanks in advance!

Its pretty simple:

function collisioncheck(obj) {
  var posX = obj.posX;
  var velX = obj.velX;
  var maskIMG = obj.maskIMG;
}

// ...

var objectToCheck = {
  'posX' : playerPosX,
  'velX' : playerVelX,
  'maskIMG' : playermaskIMG
};

collisioncheck(objectToCheck);
