I'm making a level (obviously), and there's one bit where I want the floor to block your path, but the floor disappears or collapses by triggering it to do so. Would there be any way to do this?

Care to describe further? What is supposed to trigger the floor to vanish? Don't you know which events to use or how to prepare the floor right?

Basically, what should happen is that you walk on a downward path, and it's blocked somewhere along the way by a floor. On the right on the floor, there's a trigger event of sorts, which causes the floor parts that block the way to collapse/disappear. And I have no clue what to do.

That's tricky.
What you need is an event called "Trigger Zone", which has been causing trouble to people in the past as well. I'm not sure whether you need any updates or something to use it, and I don't have a JCS here to check, but I'll try to help anyways:
As far as I remember, there are three fields to fill out for that event. One is the Trigger ID, which works just the same way as the Trigger Crate. It will trigger any Event Scenery with the same ID number.
Then there is a field that, if 1'd, makes the trigger a switch that can be turned off and on, but you apparently don't need that.
As for the last one, I dunno.
Also, I believe that the ID number has to be higher than 0, otherwise it won't work.

I hope I recalled correctly here.

Here's an example of two different ways to do that. Take your pick.

No, that is easy. Collaps scenery. Look at violets example!

Hmm..I don't quite get how the second way was done- there was no event or anything at the place to touch..

Do you see the Belt Right events? Belts can move almost any object, including Jazz, ammo, warps, collapse scenery, explosions from bullets, etc. Those particular belts move all of the Collapse Scenery EVENTS over to the dark tile. Jazz ends up stepping on all of the events at once, and the corresponding tiles collapse.
If you don't get it, try editing the level randomly until it makes sense.

...is there any place where I can read more cool stuff like this? Please?
