State 18 - Burning
state: 18 creates the "burning_smoke" from broken_weapon.dat. An itr: with this state can also hit teammates, and if you spawn another object with state: 18 , you can have it hit yourself. However, be aware that some effects (namely, effect: 22) will disable the self-hit function of state: 18.
Technical note
The fire state uses y-axis-velocity but has no direction control.
There are 4 frames representing the following:
203: Upward fire 1
204: Upward fire 2
205: Downward fire 1
206: Downward fire 2
Changing frame 203-206 to use state: 15 disables the state machine.
When a type: 0 character is in state: 18 and in frame 203-206, the next frame is determined by current y-axis speed.
If character is going up, next frame will be 203/204, otherwise will be 205/206
The exact frames are not confirmed and it is unknown if non-type: 0 share this property.
A state: 18 character landing will always be directed to frame 185 (forward bouncing)
state: 18 characters are immune to itr held by state: 18, 19 objects and itr with effect 20.
state: 18 characters can hit projectiles (example: soul bomb's explosion and firen's inferno), itr effect: 20 doesn't hit projectiles though.
Note that state machine doesn't change frames if characters is rising in frame 203/204 or falling in frame 205/206
