  1. i think you should add this but its a tutorial though with a script http://armedunity.com/topic/6464-tutorial-grenade-trajectory-line-prediction/
  2. i was making a 2 way teleport pads for my game and when the player enters the collider 1 it sets a bool on collider 2 to make the teleport pad 2 ignore the player when he is sent to it , however this made problems because OnCollisionExit wasnot called or something on the first Collider so you couldnt repeat the process the only way i managed to fix this was by destroying the collider every time and adding a new one to reset it. and it worked very smoothly a 2 way teleport system. just saying maybe someone can find this useful.
  3. i was trying to fix it and the whole thread got messed up xD i fixed it now
  4. This tutorial will show you how to predict the trajectory of a grenade or any other projectile. I used simple cubes as path points in this tutorial you can change that to any prefab you would like or you can use the LineRenderer.

  5. have you heard of a program called filter forge it can generate textures from texture filters made by the community and it even supports maps like normal maps
