Source code

A material that acts as a spawn point for the STKM. Only one pixel of it is allowed to exist in the playfield at a time (and it's also the material that is placed instead of STKM when trying to place one with a brush).

Whenever the STKM dies (or disappears / is removed from the playfield), the STKM respawns at the SPWN it was originally created from with the head being on the SPWN particle.

If STKM dies and the SPWN it was created from is gone, the STKM never respawns.

The equivalent of the SPWN for STK2 is SPWN2.
