Today, I found myself stuck with 5 blaze spawners in an immense ditch producing nothing but air itself, but in this case, being that its a chocolating game, nuffin. At first, the blazes were spawning without problem, but when i found myself being shot at by blazes I finally realized my foolish mistake. Blazes fly so a spawn trap is useless. Knowing that blazes can be killed by simply touching water or snow, I decided to add water to my enormous trap. And what do you know, THEY'RE NOT SPAWNING.

If anyone has any suggestions or currently has a Blaze trap can you please comment or message me. Hopefully no one is as much as an idiot as me <object class="emojione" data="https://resources.enjin.com/1489581540/themes/core/images/emojione/svg/1f61b.svg?0" type="image/svg+xml" standby=":p">:p</object> Thanks

Bear in mind they need to spawn on dry land, spawning on water won't work.

They only spawn at light level 11 or less, so think about that too. Torches emit 14 light so they need to be a minimum of three blocks away from light sources.

I have a blaze trap that you can look at message me in game =D

Blazes need dry land to spawn and a light level of 11 or less. They try to avoid water aswell... just have a small spawn box.

I just built the crusher in the video since I'm completely incompetent at designing either mob grinders OR redstone stuff, and it works great. The only problem is that you have to cruch them 3 times instead of once in order to get their hp low enough to kill with 1 hit, not that its a big deal though.

The Video shows how to make a timer but you can try putting repeaters to slow down how long the button produces power to the crusher ...I have mine set up at one hit and i wait then i killem

Yeah, I just made the wiring exactly like it is in the video though. I dont really know enough about how it actually works to want to risk altering it when it works good enough for me as it is.
