Use two constrains

SLOCM3Z

Hello,

Is it possible to constrain x and y to a real attribute? I did this: "Constrain Attribute : game.Center" :to: "self.x - self.y"
But all I got were a bunch of negative numbers behind half of the screen. Can someone help me?

Thanks

Do you mean the X and Y positions of an actor ? If so, the yes, you can constrain them to a real attribute.

It's hard to make any kind of suggestion as there is no way for people to know what the result should be as you've not said what it was you were expecting to get, or what game.Centre is, or whether self.x and self.y are moving or static . . . etc.

@Socks. Sorry, I now know I could have been clearer. I was expecting the X and Y to be measured with one real attribute. But I guess I can't do that and I will have to do 2 real attributes.

Thanks!

That still doesn't really mean anything specific.

Measured how? Are you trying to determine how far apart their values are? Why are you wanting to constrain an attribute's value to two different values? It's certainly possible but it depends greatly on the answer to those questions.

I wanted x and y to be the same thing so that I could say "when game.PlayerX & game.PlayerY" = "game.Center(portal's X and Y)" :do: whatever. But that can't work. I hope you understand that time. I have no other way of describing what I want. I was just wondering if x and y are measurable at the same time so that I don't have to make two attributes. But I am fine with doing so. I was just wondering if it is possible. I will just do "When game.PlayerX and game.PlayerY" = "game.PortalX and game.PortalY" :do: whatever

Thanks!

You have two options:

1. Unlock one of the actors (the player or the portal) in the scene and access the other actor's self attributes through the Current Scene-->Layers-->[layer name]-->[actor name] section of the Attribute Browser. This requires no additional game attributes but it does require creating an "instance" of the actor (by unlocking it) which means that that specific copy of the actor in the scene may have unique rules when compared to the "prototype" for that actor.

2. Create game attributes for each actor's x and y positions as you've mentioned and constrain these game attributes to the actor's self attributes.

@tatiang Thanks. I have it fixed now. Sorry about my weird descriptions on how I wanted to do things. Thanks for your help!
