Hi, I want to create a radar that works without power grid, however when I place it with 0kw consumption setting the game crashes. I tried making it "solar" with 1w consumption but that didnt work- didn't crash the game tho. Is there a way to modify the energy source to allow it to function without power? I need it to scan only nearby sectors and only for a short duration (implementing charting will be more problematic)

Probably no. The game have things like this hardcoded to the very depth of it.
This might have been uncalled for, but the following statement

Creative mode mod has entities (including radar) that run without power, with power flashing icon still present.

Well then, maybe I don't belong here or I'm really slow because it took me more than 15 to understand the code lol.... Much thanks for the work! btw, the variable e is never used, why is it there? to verify the r.next is there to simulate the radar scanning sector by sector? that's elegant!

those can be removed with render_no_power_icon =false, but if its there the entity doesn't work on 0 power and the work is done by scripts (like the one provided by Adil, above)

ok, i'm not a coder/modder. just trying to help.

no worries, I will probably take a look at the mod you mentioned. Thank you for info, and sorry if I came on rude, wasn't my intention. cheers.

You are welcome. Unused e is a typo, I've intended to read position, force and surface from it, not from r:
local e=r.entity
local p,s,f=e.position,e.surface,e.force
Sorry, about that.
Yes. r.next_x and r.next_y are there to keep track of the next chunk to scan.
Also, I'm lagging behind somewhat. We didn't have the `render_no_power_icon ` field back then. With that, who knows, maybe adding a buffer to the entity's power source (like roboport has) and using scripts to refill it, will suffice.
