Unity Billboard Demo
Note: this project uses Unity 4.6.1. Created to answer this question.
It has 3 scripts:
- Rotate: on the sphere. It rotates the sphere.
- BillboardToCamera: on each Canvas. Makes them always face the camera.
- FadeAlphaByDistance: on each Text. Makes them fade out when they're far from the camera. Caveat: have to manually set minDistance and maxDistance, values which represent the text's minimum and maximum distances from the camera. Uncomment
Debug.Log(distance)and watch the console in the editor to get a sense of appropriate values.
