`
`Description
`
`Makes a GUIText label follow an object in 3D space. Useful for things like having name tags over players' heads.
`Usage
`
`Attach this script to a GUIText object, and drag the object it should follow into the Target slot. For best results, the
`anchor of the GUIText should probably be set to lower center, depending on what you're doing. Offset is used to
`position the label somewhere relative to the actual target's position. The default of (0, 1, 0) is useful for having the
`label appear above the object, rather than appearing right on top of it. If ClampToScreen is on, the label will never
`disappear even if the target is off the screen, but will attempt to follow as best it can (for example, if the target is
`off to the left of the camera out of sight, the label will still be visible on the left). ClampBorderSize sets how
`much space will be left at the borders if the label is being clamped to the screen, to help ensure that the label is still
`readable and not partially cut off. This is in viewport space, so the default .05 is 5% of the screen's size. If
`UseMainCamera is checked, the first camera in the scene tagged MainCamera will be used. If it's not checked,
`you should drag the desired camera onto the CameraToUse slot, which is otherwise unused if UseMainCamera is
`true.
`
`Note: This script also works with GUITextures.
`JavaScript - ObjectLabel.js
`
`var target : Transform;
`var offset = Vector3.up;
`var clampToScreen = false;
`var clampBorderSize = .05;
`var useMainCamera = true;
`var cameraToUse : Camera;
`private var cam : Camera;
`
`// Object that this label should follow
`// Units in world space to offset; 1 unit above obj
`// If true, label will be visible even if object is
`// How much viewport space to leave at the borders
`// Use the camera tagged MainCamera
`// Only use this if useMainCamera is false
