Sentry Turret Problems

[SmokeLuvr1971]

Wanting to make use of these as a killing mechanism in a multi- soul cage mob drop farm. Turrets randomly die for no apparent reason [no mobs present] [ physical separation from environment].

Originally turrets were ringed around the spawn enclosure, directly adjacent with each other, with iron bars in from and opaque blocks behind/below. After first round of random turret death, turrets were confined to single side of enclosure only, but still side-by-side. Next tried separating each turret by opaque blocks [2 high]...and they still randomly die.

Then I discovered the config. Changed turrets to be invincible [rest of config is default]. Now they glitch into the floor.

I can redesign and do want I need without the turrets, surprised no one else has experienced this. Single-Player world using 1.4.7 Ultimate pack, if that matters.

Turrets die if they're touched. By anything at all. You touch them? They die. A mob lightly brushes agains them? They die. I suspect they could be killed by thier own bullets as they come out thier chamber... I find turrets too shoddy in that regard for anything lasting.

This does not explain why they're falling thru the floor when set to be invincible.

They are entities, and thus prone to the same falling-through-the-world problems as carts, golems, and dogs.

The turrets are fun but they are really designed to operate like they do in portal so people can make fun portal based maps with them. That is what they are best at. Direwolf20 used the pellet launchers in his mob spawner for his current lets play and they looked fun and effective if you want to use the portal mod for your farm.

Yep, I'd suggest the same as casilleroatr - use the HE pellet launchers for the mobkilling part. We have two public spawners on Resonant Rise TS1 - both make use of those. Very effective and no feeble Turrets needed. Plus, they are not very expensive either. =)
In my SSP worlds as well as on my SMP servers I at least once in a while try to do something with turrets - but up to now, it usually gets very frustrating very fast. So, until they are made a bit more sturdy, all I do with 'em is place down a few of those toasted ones. Because I like them. But that's about it.^^

If you want turrets, try this mod http://www.minecraftforum.net/topic/562836-152-spmplan-turret-mod-v301/

Adds a lot of turrets you can build and upgrade, can be quite expensive on resources, but quite fun. Just don't use the Flamethrower, as the flame entities are not totally despawning until they slowly fall out of the world.

Using Turrets are inherantly flawed and fragile. You may find it'll be better to use melee turtles and conveyor belts/water/etc. Turtles will keep items that mobs drop and using wooden pipes on them will take items from them.

If you don't know how to program them, here's a short and simple algorithm I use.

Spoiler

while true do
  while turtle.detectDown() ~= true do
    turtle.attack()
  end
end

This algorithm is a loop that detects the block below it. (turtle.detectDown()) If there's a block below it, it will attack any entity close to it. (turtle.attack())
This eliminates the need to faff on with config files to make it player friendly.

Program them by opening the turtle gui and typing in "edit startup" without the quotes. startup can be changed for any name of the program you'd like to call it. Type in the algorithm shown, then click ctrl. This'll give you the option of saving or exitting. You can choose between options with the left or right key. Save it, then exit to the first gui and type in "startup" without quotes or whicever name you chose to call your program and the turtle will start following the algorithm if it's done correctly until the turtle is broken by the player.
