I don't understand how to make dynamic lights, you can link me to a wiki or point me to the stickies but I still won't understand it. Can someone please either make an example WAD or in-depth describe how to use them? I'd prefer an example and I think that would also be easier on whoever (If anyone. ) helps me. Thanks in advance.

Demonstrates:

Static white light
Static colored light
Sector brightness relative light (Phased light sector)

Wow, that was incredibly easy, I feel stupid now.. Thanks for you help. xP

Quick Question:

Do the dynamic lights in GZDooM make openGL cracks light up like they do in Legacy?

I hope not.

There are no cracks like in Legacy. They are the result of a cheap and imprecise algorithm to polygonize sectors. GL nodes work differenly.

But even if there were - no. GZDoom's light polygons are always the same as the walls.

Well, since it's about the topic of the thread, I figure I'll ask another question to bug you guys with. Is there any way that I can keep the light from going through walls? Like linedefs having a property "Block Light" or something.. That would be nice.

No. Doom's level data is insufficient to do proper light clipping. You'd need much more complex data structures to handle that properly.

Speaking of Dynamic Lights, for some reason, my Pulsing Lights don't work anymore.

Flame Spawn, is the angle set to 90?

Uh, no...why does it have to be set to 90? 0_o

i don't know why, but it works on 90. i think it has to do with the pulsing speed.

Alright, thanks.

[EDIT taken out]

any time :p

add this in script

Vavoom's light types can also be used but they work like regular dynamic lights.


thing 1502 "Vavoom static white light"
{
arg1 "Radius"
}

thing 1503 "Vavoom static colored light"
{
arg1 "Radius"
arg2 "Red"
arg3 "Green"
arg4 "Blue"
}
