Command Signs
-
Some people have been suggesting a paritcle that, when sparked, executes a console command. Problem: How will it know what command to use without massive lag?
My answer: Use signs! They are formatted like:
{exe:set type fire none}
and show up as
set type fire none
in pink text. When they are sparked, the command is executed.

This is a rejected element: https://powdertoy.co.uk/Wiki/W/Previously_requested_elements.html#CMND

We don't want to add anything to the game that can run console commands or change arbitrary properties of elements. It exposes mechanics such as tmp / tmp2 too much and prevents us from changing things with how elements work without breaking saves.
Also, it would make the game much more complex, users would have to understand the properties of all the elements to understand saves that use command signs, or make new ones.
