Sprinting stops as soon as you touch another block

Intentional.

This is intentional, it's probably to avoid sprinting animations even when you are running into a wall. Just hold control and w instead of double tapping W

Can confirm in 20w51a, however, this is most likely intentional.

Has this ever been confirmed to be intentional? For hitting a block straight-on, I can definitely see it being so, but simply brushing against one definitely should not cancel it.

This may be causative of MC-199874.

Also worth noting is that Bedrock Edition has a tolerance for this, in that sprinting is only cancelled if the angle is far enough into the wall.

Can confirm for 1.17. Relates to MC-11608

Fixed in 21w38a

what angle is it supposed to be fixed for? every test i've run shows it still happens in 38a.

5° according to slicedlime's video.

ah, so it's only a very slight angle. that explains why i couldn't replicate it, i don't have the time nor patience to be that exact lmao
