What function should I use to set light to an object?
I've tried dbMakeLight and it works as I want it to, but I can only make 7 different lights with it.
And I need ALOT more light objects than 7

If you're using the hardware lights, then you are going to have to move them around depending on where you are in your scene. 7 is the hardware maximum.

The only way around this is to use a level editor with light-mapping which will give the impression of scene lighting by embedding the lighting into the textures. Try DeleD http://www.delgine.com/, which is a free and easy to use level editor with light-mapping and has a plugin for exporting .dbo files.

The thing is that I make the lights in-game, I'm running around placing objects and some of them are supposed to make light.
And I would use more than 7 lights in the place I am in the game, they're just small torches supposed to give a little light.

So isn't there any other ways to do it?

If your scenes are pretty much closed off (ie rooms) you may get away with it. Apart from that you may have to cheat with some of the effects you're after. Particles can simulate lighting but you might have to 'flicker' the ambient or local light to that object.

I'm sure there's tons more ways to cheat with lighting effects but I've not got that far myself yet. Local lighting and particles are about as far as I've studied, and light-mapping.

Thanks for helping, but I still don't know how I should do it.
I'm just trying to create some random particles using dbMakeParticles() etc, but that doesn't give any light.

Sorry for being noobish, I haven't really been programming for long.

We all start somewhere, I did too and didn't have others to ask.

The particles won't emit light so you will have to add the light manually to where they are placed.

Using the hardware lights will limit you. Going from room to room, you will need to reset the lights to the new room.

ie.

light on ceiling
light from holding a torch
light from a tv or monitor screen
light from particles used to emulate a flame

Most of the above can be placed into a light mapped texture. But doing that will be at the expense of shadows. Although as you may notice, most games do not use 'very real' shadows anyway from all light sources.

I would check out something like DeleD first and see the effect the light mapping gives you and then add the extra lights when needed...
