Autostep

autostep controls the maximum difference in height at which a player will "step" onto a surface without needing to jump. The default value is 5120. Note that autostep applies to view/wall aligned sprites and regular sectors.

Making the value smaller allows the player to climb higher sectors and wall aligned sprites, while a larger value means the player will not be able to climb over smaller and smaller heights in sectors and sprites.

A value of zero means the player can cross a sector with a difference of -9216 z units, and any other value would be added to that difference. For example, the default value of 5120 means the player can cross -4096 units.

If you are making a permanent change to this value, it is best to do it from EVENT_ENTERLEVEL so the game never overwrites your value with the default.

For above water sectors (lotag 1) and floor aligned sprites (cstat 32) (see spritebridge) please see autostep_sbw.
