Ok so heres what i want:
Im making different lvls for my game and i want for when the scene to start for example: the word LVL 1 appears on the screen and it then after a few seconds it dissapears and the lvl is playable. How would I do this?
Why do you hate the letter 'e' so? It never did anything to you.
Search the forums and/or UnityAnswers and/or the scripting reference for GUI, text, and pause. If you have a problem implementing it, we can help, but there are already many, many topics on each of those things.
Also go through at least one tutorial (3D platformer is a good general-purpose one), since they give you A LOT of practice (and the 3D platformer tutorial actually covers all of the questions you asked)
