just now I was exploring a cave system, using the new 1.4 patch, and I came across a lot of creepers. luckily it was only a tiny hole into the cavern they spawned in, so I could take them on one at a time. But, one creeper got near me and was hit off to the side before it finished exploding, and another creeper took its place. when I killed this second creeper, the first came back and exploded almost instantly. I noticed it looked swollen like creepers do right before they explode, and thus I have determined that it somehow "held in" the explosion.
I don't know if this is a bug or intended or something I missed, but instead of canceling the explosion, it paused it, and when it came back I had no time to do anything about it before it blew up in my face. Anyone else have this happen or know what's going on?
The same thing happened to me. I was walking into my Church of Notch, turned around to close the door and noticed a Creeper had been following me the whole time. I closed the door while it was "puffing up" and it stayed in that state until I killed it. Very odd.
I posted in another thread about this, but allow me to try to explain. The following information might be wrong, but damnit, I'm posting.
See, all creepers have a counter. It ranges from 0 to 30. When it hits 30, creeper goes bang. I believe it counts up at 10 "ticks" per second.
FUN FACT: The creeper's "sssss" is not one sound effect. It's the same sound, played for every tick the counter makes.
I'm not sure when it got changed, but it used to be that when you got out of range of the creeper, the counter instantly reset to zero. People got used to it - you could let it almost explode, run away, and repeat as many times as you wanted.
I think it was 1.3 that brought the change of creepers. Now, when you run out of their range, they start counting down at a slower rate then when they started.
So what's happening here is that people hit the creeper while it goes to 25, get out of range, expecting the creeper to reset the counter. But actually, the creeper only just started to count down. So they go back in, expecting three seconds again - when in reality, they only have one.
Hope that didn't sound too technical. I don't know the rate at which the counter ticks down, but it must be slower than it ticks up.
