I support but this can be done with zombies.
You Need the Day/Night Mod
0 On 6pm-Named brick>Zombie Spawn-Setvehicle-Zombie Tank
1 On 6am-Named brick>Zombie Spawn-Setvehicle-Zombie Tank
We need this done with bots as you can see we started the bots as shown in blockocrafter's post above
Also I got the
creeper face!
\\Events for bot's below Blockocrafter:....VVV
OnTime8:00 > named brick Bot(name the all the bots spawns "Bot" > Bot spawn
OnBotSpawn > namedbrickBot> SetAiMovent> Run
Onbotspawn> named brickBot >
additem > (weapon of bot here)
Also different brick name for each bot spawn because some do not have weapon and some do not even have a weapon
For spider use item dragon claw
For skeleton use bow
For creeper im not entirely sure
For zombie use item dragon claw
For that um white floating suid thingy use item dragon fireball
