Please can some explain me this lines in the setup.ini?
lightmapsunx=0
lightmapsuny=-1
lightmapsunz=0
lightmapsunr=0
lightmapsung=0
lightmapsunb=0
I read the setup description, but I'm cofused if the sun point in fpsc is really working?

I am not sure because I have not messed around with it, but just guessing...
the _X _Y _Z would be coordinates for the Sun's position in the 3d environment, and the _R _G _B would be the values for the color assignment in an RGB triplet form.

The sun is a directional light, and will effect everything in the environment. The X, Y, Z settings will set the light's direction normal. So, the current setting of X=0, y=-1, z=0 will make the sun's light shine straight down.

NOTE: Since the coords are a "normal" then the vector length should (by definition of a normal) be equal to 1. So to give a 45 degree shine on the X axis you would use the settings: x=0.707, y=-0.707, z=0 (Someone can check my math on that, lol) Though, if I recall FPSC should let you just use: x=1, y=-1, z=0. To get the same effect.


And, as Conjured pointed out, the R G B values are for the color.

Thanks for help, but it doesn't work.
I set RGB to 255, 214, 077. The coordinations as you written to 45 degrees (so x=1, y=-1, z=0).
I tried it in test mode but with no solution (like there wasn't any light source). I also move the player mark to the lower floor.

I'm thinking about the coordinates - doesn't it meant as 1 number is every square or layer? And how to correctly calculate the sun angle?

Maybe one could email knxrb, hockeykid or Marc Steene and ask them if they know anything about it? I'm sure hockeykid is busy starting school now so maybe one shouldn't bother him.

This feature definitely sounds interesting and therefore I'm going to take a look at the source code myself.

Addendum:

It seems that it should work in test mode but have you tried building a stand-alone game with those settings.

I looked at the source code. The only code that might do anything is the following:



Add Directional Light is a special LM command that is probably found in a DLL specifically for FPSC and not DBPro. It is definitely outside of the scope for DBPro because there is no help available for it. So, I'm not sure exactly what the x,y,z values should be in reference to the 3D coordinate grid. Also, it is interesting to note that the rgb (I'm sure that's what they are) are divided by 100.

Plystire, I'm clueless in Lincoln. Any ideas?

This is what Lee has told me about it:
Quote: "They were added for DarkLIGHTS but are not exposed in the engine, and have
remained as default values since then. Consider them an unimplemented feature."

DarkLIGHTS is in the engine already, it's a lightmapping plugin and not a dynamic lighting plugin.

but, will we ever have the ability to direct ligths?

-Why didn't God take gaga,justin bieber or kesha instead of Randy Rhoads, Cliff Burton or Dio?

Already have that ability to an extent, using light cones, cylinders etc to create spotlights and other directional lighting (as I said to an extent)

Those type of lights are not "directional lighting", though, Nbt.

Directional lighting is a global lighting that effects everything in the scene... it does not come from a specific point and so does not require a position in 3D space. All that it requires is a direction normal to specify which direction the global light shines in.

Quote: "note that the rgb (I'm sure that's what they are) are divided by 100.

Plystire, I'm clueless in Lincoln. Any ideas?"


Try using 100 as the max value for colors in your settings. It is likely that DarkLIGHTS is expecting a normalized value for color settings (0.0 - 1.0)

Also, please note that since this is the sun, you may need to use an outside scene to see if the lighting effect is working, as I'm unsure if indoor areas will be effected by this (what with having a ceiling and all )

If that doesn't work, Lee may have disabled this feature elsewhere in the source as I am positive the feature itself functions with DarkLIGHTS. (I've used this in a seperate project)
