Mostly. They are now const but only in graphics functions called from secondary Renderers. The primary (main thread) Renderer still allows graphics functions to mutate Simulation; this is required for correct in-PIPE rendering of custom elements.
Most of the switch statement in create_part is gone. There's a few others that I will get rid of in future commits. There will also be a CreateAllowed function, and a ChangeType. ChangeType will handle stuff that is duplicated in both create_part and part_change_type. Considering making a Destroy function instead of ChangeType, though.
Later on, Lua events will be made for all 3
Credit to jacksonmj for the original design of all of this, I copied it into my mod years ago
The rest will will in a commit soon that adds the Create event and some other stuff
Lua events will come after that
PLSM default temp lowered to MAX_TEMP
Also add some new FILT modes, and make FILT modes affect BIZR and
BRAY colour in the same way as they affect photon colour. Photons
passing next to DTEC will set the colour of all FILT in a straight
line starting from any FILT adjacent to the DTEC (a bit like an
ARAY beam), and the exact colour of the photon will be used for
FILT interactions instead of the colour based on temperature.
FILT tmp=4: red shift, tmp=5: blue shift. Size of shift determined
by FILT temperature. tmp=6: FILT has no effect on photon colour
(possible before by using invalid tmp modes, but here's a supported
method of doing it. Invalid tmp modes should be automatically replaced
in existing saves).
Also, FILT mode is now described in the HUD.
