Mac support is a bit behind Blockland
I believe my opinion is credible
Sry, i don't consider mac users a credible opinion when it comes to gaming
As a willing mac user, you already decided to give up gaming.
Valid point is valid.
There's two ways of making working ladders in Blockland.
1) (Which is mostly if you are in YOUR own server, and have the Mision Editor) Make aphysical zone with -1 gravity, or upward force.
2) (For playing on other servers, or any without f11) Use 1x1x1 print bricks and 1x4x1f to make the ladder, then crouch, jump, and walk forward to go up.
