Mind the Gap... putting rotating pieces into a platform.

Archive: 4 posts


I'm sure this is a newbie issue, but I can't seem to get my head around it.

I'm working on a new level. One contraption I want to put into it is a "spike pit" that can be rotated into a "bouncy pit". The problem that I'm having is when I embed the rotating piece into the platform, I can't get a nice fit without stopping my rotation... I'm forced to put a little gap on the rotating pieces and I'm not happy with the way that it looks. On top of that... I also seem to need a gap between my bouncy pads, and this can lead to a situation where the player lands in the gap and doesn't bounce!

Like I said, I'm sure you pros will have a quick and easy fix... but I'm just stuck. Any ideas?

In my experience, the gaps are necessary, especially with curved/circular shapes. Of course, there are no true circles in LBP - just many sided polygons. So when the angles of those polygons collide... well, you've seen the unfortunate results. Sometimes removing most or all friction (with glass material or with a material tweaker) will help with this problem, but mostly this applies to smooth, straight surfaces. The gaps don't need to be very big - I usually find them acceptable in appearance when they are very small - but again it gets harder with circular shapes. If the gaps really bother you, you could always use some sticker material at the full size of the circle (so they touch) and glue it to your ever-so-slightly smaller physical shapes, then sticker it accordingly to look like solid material (or use decorations to the same end). If you've made the gaps small enough, sackboy shouldn't even register that he's stepping on a gap. You will have to go off-grid to get a tiny gap. When re-sized off-grid, a circular object will shrink toward the center. One trick is (as I mention above) to glue a copy of the shape at full, grid size using invisible sticker or holo to the shrunken version of the same shape. Then you can still use the grid for symmetrical, balanced layout.

Don't know if this is helpful - you probably already know all these little tips. But hey... I tried.

You'll want to cut your flat-standing platform bits within the circles deeper than the halfway point, so that when the new content is added (platforms, spikes) they are flush with the halfway point and therefore can rotate without bumping into anything else.

Better explained in visuals:

You can also resize and embed the bounce pads so there are two per circle (four total) which reduces their "thickness" so they won't collide and can be fitted more closely together.

And, as an alternative design, you can use a flat piece and glue spikes to one side, and the bounce pad(s) to the other side. Put the rotator in the center of this and you're good to go!

^ Nice illustrations! It does seem like you have the bounce pads too far above the 'center' line, so arbiekko's solution should be an improvement.2012-07-30 03:45:00
