Getting the player to look at the camera

Matchewawa · 09:54 PM

I've been planning my next game project in Alice as I approach the finish of my first big project (It's called Bravura, I'll probably post it within two weeks of now). My next project is inspired by the popular Steam game, Magicka. I want the character to always face the mouse, which I'm sure is possible, but I don't know how. I know I can get some hints from something I found a while ago that is a code for a First Person Scroll, where the mouse allows you to look around, but I don't get it. If someone could take a look at it (attached) and if they get it, explain how I might be able to make the character face the mouse, then I would be very grateful. I'd definitely put you in the credits! lolFirstPersonScroll.a2w

Why don't you look at some of the other games on the boards that actually have the exact code you're looking for?

Like this one...

Thank you very much. I'll be looking this over for a while, cause I only half get it. I just want to know what I'm putting on so I can tweak, add, and optimize if needed.

Can you explain the equation that you used to move the pointatdummy and the turretpointer, where you had 4 equations, one of them being "( ( left dist - 400 ) / 58 )"

Here's what I have so far, but the wizard is acting screwy. I don't fully understand how the look code works, so I can't figure it out (and I really tried).

That is the equation that uses the centerpoint of the screen to determine where to move the object that the turret points at. The number 400 is half of 800, which is the first number in 800x600, which are the dimension of my Alice window when I play (you can change those dimensions in the preferences menu).

OOP! Found the issue. Pretty obvious one. It was only reading the leftDist variable, which was applied to all four of the methods moving the dummies. I just needed to change the bottom two to the topDist variable so it reads the distance from both the top and left edge.
