The lix mechanics treat a pair of high-res pixels at coordinates (2x, y) and (2x+1, y) as solid if at least one of these pixels is covered by terrain.
Given that the borders of the blocks 01 to 08 of the oriental style do not have straight edges, this has some interesting consequences for climbers:
- Climber may never climb any side of the big block 08 nor may they climb the right-hand side of the block 05.
- For all other blocks (including the left-hand side of block 05), it depends on the coordinates of the block whether a climber may climb up or not. If the block is positioned at an even x-coordinate (in high-res), then the lix may climb up the whole block. If on the other hand the block is positioned at an odd x-coordinate, the climber will soon fall down.
As a player of a level, one cannot tell whether a given piece has an even or odd x-coordinate. So one never has any chance to determine in advance whether a lix may or may not climb such a block. The only way to be sure is to actually try to climb the piece and see what happens, or to peek into the editor.
I don't have any suggestions yet how to improve the situation, that do not sacrifice the look of the oriental style or will likely impact existing levels.
