(whoa, this just turned into a wall of text. key points in bold)
Here's something I just found while using the cursor steel-digging glitch on Mayhem 12. Keep in mind here that
the steel area matches up exactly with the steel terrain.After using the glitch to get through most of the steel, the remaining piece is at least 8 pixels across (this is the furthest you can get with the first digger still under the cursor). To get through this width of steel takes at least two basher strokes (the most you can take out at once is 7 pixels), which should mean the basher doesn't work at all. And yet it goes through.
I'm testing things as I type this. It only seems to work when the basher is above the level of the floor where the exit is. If I try it at floor level, or more than 4 pixels above, it doesn't work.
And it gets weirder. I move the exit away and it stops working. If I move the exit to the left, it lets me bash through the left part of the steel. And a bit more testing shows that it's
caused by the exit top, not the exit itself. Other objects don't seem to work. Wherever I move this object (or place new ones), the steel becomes destructible below the left side of it.
Now I'm sure you're curious and want to see this for yourself. Open up the level (Mayhem 12, "The Far Side") in Lemmix and do the following:
- Move the top part of the exit down 4 pixels.
- Copy the object and place two more, one 8 pixels to the left and the other 16 pixels to the left
- Run the level and bash through the steel.
And then move some things around to see what happens.
I'm going to test it in DOS now. I have my doubts as to whether it will work...
EDIT: Wow, it works in DOS.
However, I've only got it to work in the dirt tileset. It works for miners, diggers and bombers too, if you use them in the right spot.
Mayhem 12 is the only level where this has any effect. I checked Tricky 27, but the areas don't overlap at all. In theory, this works for VGASPEC levels too. The original special graphics levels don't have steel though. (Don't worry geoo, Supaplex Tricks isn't affected
)
I've pinned down the exact area affected. See the attached screenshot.
The trigger area on the left is the area where steel is canceled by the exit top piece (I placed a coupe of rock traps to make this). It lines up with the DOS grid, so (for example) moving the object one pixel to the left has the same effect as moving it 4 pixels to the left - the breakable steel area moves left by 4 pixels.
