This should be less of a drag on the playsim than having each light a separate actor. A quick check with ZDCMP2 showed that the light processing time was reduced to 1/3rd from 0.5 ms to 0.17 ms per tic.
It's also one native actor class less.
The loop never checked if the item was still valid and would continue to try to use it, even after it was removed from the inventory and destroyed.
As native code this just failed silently, but with the VM it needs to be explicitly checked.
Add 'useowncoloradd_{top,mid,bottom}' sidedef properties to the UDMF
spec
Only use side's additive colors if 'useowncoloradd_(top|mid|bottom)' is
set.
Rename UseOwnColors flag to UseOwnSpecialColors
Add UseOwnAdditiveColor flag to side_t::part
Add EnableAdditiveColor to side_t
Add Side.EnableAdditiveColor to ZScript API
Sector.SetAdditiveColor actually called Sector.SetSpecialColor
Add use boolean property, used to determine whether or not to override the sector's additive wall colour with the side's additive colour.
The new specification is more flexible, and allows assigning additive
colors to individual parts of a sector (walls, sprites, flats) and even
individual parts of a side (top, middle, bottom)
Add AdditiveColors arrays to sector_t and side_t::part
Initialize AdditiveColors arrays to 0
Export AdditiveColors to ZScript
Save AdditiveColors in saved game files
Use colors from AdditiveColors arrays when setting the additive color
for the render state
Add code to parse the new UDMF additive color properties
Remove additive color slot from sector color/part enum
Add SetAdditiveColor to sector_t and side_t
Add GetAdditiveColor to side_t
Export new methods and additive color arrays to ZScript
Rename ColorAdd to AddColor
Add AddColor to FRenderState
Tweak SpecialColors array in ZScript to include the additive color
Add uAddColor to the shader compiler
Add uAddColor to the texel
- TriggerPainChance(Name mod, bool forcedPain)
- One exception: PainThrehold is only checked in ReactToDamage, since this function does not require checking damage amount.
Unlike everything else from the IWADs this had to use the 'light' keyword in ZScript because this is merely a base class for many others and the light definitions here need to be inheritable.
Many uses of random() & value have been turned into random(0, value).
This is not only more efficient, it also ensures better random distribution because the parameter-less variant only returns values between 0 and 255.
