I have a few questions here, mainly for level building.
How far, from the front of the first brick to the back of the last brick, does a builder build in pixels?

What's the bashing height in pixels?

What's the digger in pixels?

It's mainly because this stuff was included in lemmings PS2 level designing as guides, but not in lemmini, so I need a little help.
(The measurements here, even the ones for Lemmini, use the pixel size from the original games. To convert them to Lemmini pixels, multiply them by 2.)

The width of a builder "staircase," including the widths of the first and last bricks, is 28.
What's the bashing height in pixels? 
In the original games, it's 9. However, in Lemmini (but not SuperLemmini), it's 10.

You mean the height of the digger mask? That's 3.

More likely he's asking for the width which would be 9 (in the original games anyway).

Yeah sorry, I worded that wrong, I meant the width.
Also, would it be possible to get the height a builder builds as well?
12 steps, each step is 1px tall, 6px wide, and 2px to the right (or left) of the previous one. As usual, double those for Lemmini resolution. This means the bridge as a whole is 12px tall and 26px wide.
(For the two similar skills in NeoLemmix; the Platformer's bricks are the same dimensions as the builders, except being placed 3px to the right/left instead of 2px, and obviously being placed at the same height instead of 1px higher; so the overall size is 1px tall and 39px wide. As for the Stacker, its bricks are 1px tall and 3px wide, and placed directly in a stack of 8 bricks, so overall it's 8px tall and 3px wide - do note that if the lemming is right on the edge of a platform or slope, the stacker's stack starts one pixel lower.)
Thankyou!
