I probably got some things backwards, but I hope it gets you the general idea. I guess I don't have Unity in front of me, but I think that's the general idea.
Save the updated vertices back to your mesh.įrom then on, just get the Scaler component attached to your objects, and call the Scale function passing in the scale. Add it to the anchor position and that is your new vertex position. You'll take subtract the saved anchor position from each vertex position, and multiply that value by your scale. In the scale function, you will look through all the vertices in the mesh. Then, create a Scale function, that accepts an amount. So, if your object is a cube, and the anchor is at the bottom left front corner (um (-1, -1 -1) I believe).Īlso get a reference to the mesh on object A, and save that too.
#Unity change the anchoring of a cube code
Attach your code editor to the Unity Editor. Copy the below code and paste it into MenuScript. Click on the Canvas in the hierarchy and add a new C script named MenuScript. For example, you can change the default cube to be aluminum with a 1-centimeter bevel radius. And i have to add boxes with different dimensions in it. Right-click the Panel and choose UI Copy the text and paste it so you have a total of 5 Text objects in the Panel.Move each text so each one sits next to a button. Anchor Your Composition to Something in the Real World.
For example to double the size of the GameObject: transform.localScale new Vector3 (2F, 2F, 2F) Edit based on your comment: point is that i want to make a box, like a container. Save it's position locally relative to object A's position, and save that in a field variable. If you want to change the size of a gameObject in runtime you can change the scale. In the Startup function of the script, find the "Anchor" child gameobject. Or you can just add a script vector variable, that holds the anchor's local position.Īdd a script to object A, your original. What you might do is, attach an empty gameobject to your original object (Object A), and call it Anchor. I've been using Unity for a while now, and I'm not aware off the top of my head if Unity has a "Scale from position" function. If so.the only way I can think of to do this in Unity is to actually define the anchor yourself, and actually move each vertex of the box/cube/whatever away from the anchor. The other corners expand away from the bottom left corner. When you scale it, the bottom left corner stays at the anchor. An Anchor is a special component that overrides the position and orientation on the Transform component on the same GameObject. Instead, let's say you want the "anchor" to be the bottom left corner. Right now, when you scale it, all corners expand away from the center (anchor) as you scale it.
