And you could make it so that the touch-and-go platforms lift up a thwomp as a block. To activate a platform after pressing a switch,place a touch-and-go platform hidden under the switch.

I've set the y-speed of a block to 12 by editing the code and after reloading, the block doesn't move at all though the y-speed is displayed at 12!
I guess I'll do something else, but why does that happen?

[CedarBranch]

Have you checked the Acceleration speed? If Acceleration is set to "0" or anything that isn't a valid number, the Block won't move despite its speed.

[Supershroom]

Acceleration was set to "1" on all blocks. I just wanted to increase the speed and I didn't change anything else and the blocks have moved before.

[CedarBranch]

I know what I'm going to say will sound simple, but is the y-length set to "0"?
If that isn't the problem, I don't know what else to tell you other than maybe it's some kind of strange bug nobody's ever noticed before until now, but I cannot see how if so.

[Supershroom]

y-length was set to 24 before and then changed to 16 to deuce the speed increasement. So that means it's really a strange bug. But in this case, never mind.

IMPORTANT EDIT:
Actually I don't believe that a block moves the product of its speed by its length. Today I've done this:

Before:

y-speed = 8, y-length = 24

Afterwards:

y-speed = 6, y-length = 32

Both products are the same, but now the block moves farther than before! How does that happen?
If you ask, there weren't any other changes.

[Harmless]

Y-speed is how much distance the block covers in a given time, or essentially how fast the block moves.

If you set y-speed at 8 and y-length at 24 (which is less than a tile distance), then it's going to cover that short distance really fast.

If you set the y-speed at something like 1-2 and y-length at 24, it will cover that short distance at a much slower pace. I think that's the explanation for the illusion you saw of the block covering much more distance.

[Supershroom]

thx Harmless, I can handle those blocks now finely

How many frames are counted as one second for caps and switches?

another cool thing I found out, if you take a circle platform, set the speed to 180, platform count to 2, and radius to 10, it becomes a bounce pad.

If you found this all by yourself, good job

But yeah, it's a pretty well known trick already. If I remember correctly, if you increase the radius, you should be able to jump higher.
