Description of the bug

When dragged over mobs, dead king can still trample them and deal damage as if it was alive.

What's the difference with what should have happened?

It shouldn't do this.

How do we reproduce this bug?

1. Kill king.
2. Drag it over a mob, even yourself.
3. Get trampled, receive damage, laugh.

once it's dead you should maybe unregister this, or just return if it's dead however you wanna do it.@Git-Nivrak

/mob/living/carbon/xenomorph/king/Initialize()
	. = ..()
	AddComponent(/datum/component/footstep, 2 , 35, 11, 4, "alien_footstep_large")
	RegisterSignal(src, COMSIG_MOVABLE_PRE_MOVE, PROC_REF(check_block))

/mob/living/carbon/xenomorph/king/proc/check_block(mob/king, turf/new_loc)
	SIGNAL_HANDLER
	for(var/mob/living/carbon/carbon in new_loc.contents)
		if(isxeno(carbon))
			var/mob/living/carbon/xenomorph/xeno = carbon
			if(xeno.hivenumber == src.hivenumber)
				xeno.KnockDown((5 DECISECONDS) / GLOBAL_STATUS_MULTIPLIER)
			else
				xeno.KnockDown((1 SECONDS) / GLOBAL_STATUS_MULTIPLIER)
		else
			if(carbon.stat != DEAD)
				carbon.apply_armoured_damage(20)
				carbon.KnockDown((1 SECONDS) / GLOBAL_STATUS_MULTIPLIER)

maybe it also shouldn't play the trample sound if it walks over a dead mob?

[vero5123]

so like

/mob/living/carbon/xenomorph/king/proc/check_block(mob/king, turf/new_loc)
	SIGNAL_HANDLER
	for(var/mob/living/carbon/carbon in new_loc.contents)
                if(carbon.is_dead())
                        continue
		if(isxeno(carbon))
			var/mob/living/carbon/xenomorph/xeno = carbon
			if(xeno.hivenumber == hivenumber)
				xeno.KnockDown((5 DECISECONDS) / GLOBAL_STATUS_MULTIPLIER)
			else
				xeno.KnockDown((1 SECONDS) / GLOBAL_STATUS_MULTIPLIER)
		else
			carbon.apply_armoured_damage(20)
			carbon.KnockDown((1 SECONDS) / GLOBAL_STATUS_MULTIPLIER)

		playsound(src, 'sound/weapons/alien_knockdown.ogg', 25, 1)
