Light problem (New user)

[FlawlessHappiness]

But, i've seen videos of people doing the exact same thing. Then pressing the A and P button, and there comes spheres of light around the pointlights

The global point and ambient light is a feature of the level editor to help you see what you're doing without having to place down other forms of light. The global point and ambient light do not affect the maps in game, since they don't exist in game.

So i guess my level will be lit up anyway? But i have to open it in the game to see it
