acuccoder it works through DTEC serializing(there's a save all about FILT serialization) the ctype of photons into FILT so that a trail of (in this case)white FILT is drawn when the photons go next to the DTEC. And PigLover, that's ok.
creator_of_fail sorry (still angre for some reson :( )
this is FAR from being the same exact as id:2793571
PigLover5 you made a save also called "photon effect" in 2021(which has one vote, so I doubt I saw it and copied it), it shows photons being created and bouncing around a solid box while my save has dtec+filt marking the locations of preexisting photons which loop around the screen. Our saves are drastically different and only share part of a name.
Their velocity is set to two integers upon being created, this "effect" is no more complex than saying sand falls or iron stays in place.
so don't even THINK of claming responsabellaty for this or else.
i am sure that i did something like this a long time ago
