-- Hello! If you want to use any code of my mod into yours, fell free to use, just credit me tho. I also recommend you see the mods in the credits.
-- Here the code register the crouch states
freeslot("S_PLAY_CROUCH", "S_PLAY_UNCROUCH")

states[S_PLAY_CROUCH] = {
	sprite = SPR_PLAY,
	frame = A|SPR2_LAND,
	var1 = 0,
	var2 = 0,
	tics = 2,
	nextstate = S_PLAY_CROUCH
}

states[S_PLAY_UNCROUCH] = {
	sprite = SPR_PLAY,
	frame = FF_SPR2ENDSTATE|SPR2_LAND,
	var1 = S_PLAY_STND,
	var2 = 0,
	tics = 2,
	nextstate = S_PLAY_UNCROUCH
