I am making a zombie game, but the bathroom cant be goten out of! And, the other character is not there! Help!!!

Im getting an error message when I go in the house, no paramiters in make object visible function, will anyone help?

We'd love to help, but without more information about what exactly you have done (posting your actual game file would be best), we have no idea what "the bathroom", "the other character" or "the house" is, nor do we know how what object you're trying to make visible or how you're trying to make it visible.

As far as the error message, it sounds like you haven't passed the desired object to the function to make the object visible, but without the exact error message for that, I can't even be sure about that.

Again, if you could post (attach) your game file in a reply or otherwise show us at least some of your code, then we can try to help.
