Mob activation?

[Jumbo101]

Greetings!

I figured out how to
make my own custom
Mobs and I was wondering...

When you kill the custom mob,
is there anyway you can make it
activate something?

For instance: You defeat a evil wizard
and when you kill the wizard, there is
a door at the end of the room and it opens
once you defeat the mob.

Is there anyway I could do it
with command blocks maybe?

I'm sure it's possible. With command block heavy maps like Diversity and Terra Restore, I'm convinced anything is possible. Unfortunately I don't know much about command blocks and I don't know if anyone on this site does. Ask around on minecraftforum.net, you will likely have better results there.

Depends on what actions you need, really.

/d MOBNAME @a[score_health=0] on a clock, then /setblock item_name x y z set to a comparator to detect when the clock gives the signal upon death, to place the block.

However, I think doors may be one of those entity-like blocks, so it's pretty finicky. I've seen things done using scoreboards, though, so it may be possible. Perhaps an armor stand two blocks low wearing a door as a helmet with barrier blocks acting as the door closed by using a /setblock and detection clock hooked to the mob detector, then when mob is dead, have the armor stand pivot and move to look like the door opened, where th e detection clock will then replace the barrier blocks with air.

Well, is there any command you could give me for it?

Commands are dependent on what version you use and what your mobID is.

/setblock will handle block placement server-side.
/scoreboard handles how scoreboards work.
/testfor looks for entities fitting specific rules.
/summon Will spawn or place an enemy based on what specifics you wish for it to have.

You can also code your mob to summon or place a door in a dungeon/room if it's a mod, if that's your intention, and code it to only open upon the mod's death. That's if you don't want a lot of dirty redstone.

I don't do much with commandblocks, I'm(I was) more of a creative builder than a redstoner.

Sounds to me, though, that you want to use setblock, summon, testfor, and scoreboard.
