How do I return -1 or 1 by comparing positions

Hi everyone,

This sounds simple enough but I can't find a way to get a -1/1 by comparing positions.

For example, there's a player object, and when it collides with something I want to compare their X positions so if the object.x is > than the player.x, I get a 1 and if it's not I get a -1.

Any idea how to achieve that? It's probably something simple but I'm stumped!

Thanks!

round( X / abs(X)) will give you -1/+1.

round( X / abs(X)) will give you -1/+1.

Nice, exactly what I needed! Thanks!

Err after some testing I still can't get what I want. Sorry, I'm really bad at math!

This function allows me to get a -1/1 position based on the 0,0 in the canvas. I've been tweaking it to get a -1/1 position based on two objects, but I don't see how...

Edit: Nevermind, got it. I swear I tried it before but it didn't work, tried it again now and it did...

I used round((player.X-door.x)/abs(player.x-door.X))

X=object.x - player.x

round( X / abs(X))

Conditional expression(under operators).

object.X > player.X ? 1 : -1[/code:1i8lf16y]

Oh wow that's handy. Thank you!
