Bouncing on slime blocks below carpets #64

Open minoneer opened 8 years ago

minoneer commented 8 years ago

When jumping on a slime block which is covered by a carpet, the player usually bounces back up as if it were a blank slime block. However, on our server it only works for players in creative mode or with nocheatplus.* permissions in survival. Therefore I assume it is NCP blocking the bounce. This is not an issue with bare, uncovered slime blocks.

NoCheatPlus version 3.13.4-BETA-sMD5NET-b901 Spigot version git-Spigot-6c9b0a1-de5c261 (MC: 1.8.8)

Reproduced for low-fall-height (also low bounce after bouncing many times with high fall height, but remaining low height). Can you confirm that it seems to be the low-height bouncing?

minoneer commented 8 years ago

No, for me it is with high fall hights, everything above 1 block. If I stand on the block and start jumpting, it works as it should. If I jump from a hight of 1 block, I also bounce as I should. Starting from a hight of 2 blocks and up, I just land on the block without any bouncing. I turned on the logging, it logs a MOVING_SURVIVALFLY (see attachments)

On second testing run, i have it on the first bounce back from arbitrary height too. I had been testing with an altered version (roughly 908), though.

Looks like we can fix it with the new past move tracking thing.

Build 911 should fix or at least reduce the issue (only shortly tested).

Looks good with all carpets (build 913), seems that partial carpet coverage still can lead to false positives (fix following).

minoneer commented 8 years ago

I did a quick test with build 913 - seems to work as it should!

Not sure about the partial coverage, but platforms completely covered with carpets are bouncing again.

Thanks for the fast fix!
