Dynamic lights

[Harry]

Is it possible to put dynamic lights in your jdoom map without having to do all the complicated decoration definitions. or a way to blend the lights of your map because i dont like the hard edges of where different lights collide.
Can anyone help?

There is no method getting around creating dynamic lights without manipulating the illumination DEF file. As a way to speed up the process, you could create a thing and attach a decoration to it or you could load spare copies of the textures that you want to give off light into a paint program and document the coordinates. Later, you could copy the coordinates into the DEF file.

The method doominsanity (btw happy bday *party*) posted is perhaps the most flexible atm.

I presume he's talking about the sector lighting. There is no way to avoid that other than either creating the gradients yourself with loads of sectors or lighting the level one flat brightness and just using dynamic lights to brighten it up. But since the lights are dynamic, they wont have any shadowing ala quake.

Here:

Thing {
ID = "GENLIGHT"; <---- Change to what you want
DoomEd number = 21003; <---- Give this an unique number
Spawn state = "DYNLIGHT1";
See state = "NULL";

Missile state = "NULL";
Death state = "NULL";
Xdeath state ="NULL";
Raise state = "NULL";

Pain sound = "None";
Death sound = "None";
Active sound = "None";
Reaction time = 8;
Spawn health = 1000;
Radius = 40;
Height = 8;
Mass = 100;
Flags = "mf_nogravity";
}

Sprite { ID = "VOIDA0"; } <---- Change this to the sprite you want it to have in (note that voida0 is not in the doom or doom2 wad files, you have to create your own transparent sprite)

State {
ID = "DYNLIGHT1"; <---- Must be the same as spawn stage
Sprite = "VOIDA0";
Frame = 32768; <----- Leave like this, do not touch unless you know what to do;)
Tics = 5;
Next state = "DYNLIGHT1"; <---- Must be the same as spawnstage
}

Light

Flags = "lgf_nohalo";
X Offset = 0.0;
Y Offset = 0.0;
Size = 70.0; <---- The size of the lightmaps (use large sizes when using small lightmaps, small size when using large lightmaps)
Red = 1.0;
Green = 0.70;
Blue = 0.0;
Top map= "LIGHTM1"; <---- Create your own lightmap for this or use one from jdoom.wad

Side map= "LIGHTM1"; <---- Create your own lightmap for this or use one from jdoom.wad
}

Thx for that WAK, I'll try it out ASAP :D
I've tried it, but how do I make a sprite? i'll give it a go :)
EDIT: every tine i make a new sprite in ded doomsday just crashed on level entry :(
What am I missing out? well I think I am missing out quite alot because all I did was create a sprite in ded.
EDIT AGAIN: Yesss, I got it to work by making it replace the sprite "PUFF" :D

[Harry]

Heh, look at this: http://img.photobucket.com/albums/v411/Harrydude/Lights.jpg
I eventually got it to work perfectly :D

But it is a frame rate killer;)
Check your pm box in 5 btw
(unless you've fixed that too:D)

I've sent the reply ;)

Is there a way to cause the skybox or the sky texture to give off light other than a sprite?. I tried to attach a light decoration to the texture flat, but it won't illuminate. I also tried to attach one to the sky texture itself.

[DaniJ]

You can make the sky cast a plane glow (like the nukage) by adding FSKY1 to this string in Text.ded:
Text {
ID = "RENDER_GLOWFLATS";
Text = "LAVA1 LAVA2 LAVA3 LAVA4 NUKAGE1 NUKAGE2 NUKAGE3\_
FWATER1 FWATER2 FWATER3 FWATER4";
}

Also you can change the skycolour of your outdoor areas by adding eg Sky light color { 1.0 0.85 0.85 }; to your Map Info definition. Placing decor lights on a sky flat won't work.

Thanks Danni!
