Collision

by themagicalcats » Post

As of lately when playing Minetest in my worlds, usually I get stuck on blocks while walking and jumping or just going right thru blocks, it's really getting annoying.

Disable free_move (fly) or noclip while flying.

Which Minetest version, though? There were quite some changes from 5.2.0 to 5.3.0, hence using a newer version might already fix your issues.
Look, I programmed a bug for you. >> Mod Search Engine << - Mods by Krock - DuckDuckGo mod search bang: !mtmod <keyword here>

I know what he's going through, and it happens in both 5.2.0 and 0.4.16
basically, as you jump, walk, or place blocks, sometimes you'll fall through a block or place a block at your location (both feet and head)

this also happens with entities, which will get stuck inside the walls
for example the Item_drop mod will throw block entities as they're mined, and sometimes these entities will get stuck on the wall:

This sounds like it might be related to the various collision fixes that were merged in 5.2. I can't remember if those were eventually reverted, but I do seem to recall a number of reported issues.

Version before 5.2 had this issue.

That's really fascinating, because I've been playing on a fork of 0.4.14 for several years and never experienced these anomalies with the original collision processing. I wonder what could have changed between 0.4.14 and 0.4.17.

5.3 actually. In terms of collision detection 5.2 is identical to 0.4*

If there are any major problems with collision detection in 5.3 they may be related to --ffast-math compiler flag, be sure to disable it.

It all happens in each of those versions, doesn't matter which I can go thru blocks or just places blocks in myself.

I wonder if accuracy of collision detection can be affected by some other factor. I can't think of any other reason for why only some people would experience this behavior but not others.

This has happened to me before when a mod sets the collisionbox of a player to nothing

Re: Collision

Okay, so today, yes I noticed 5.3.0 has fixed the collision some more but one problem is still here, I'm able to place blocks in my same area, like for example I can place blocks within myself, is it possible that this can be fixed so you cannot place blocks within the player? Because whenever I play I always end up placing blocks in myself while towering up or just in general building.

I thought you said above on July 25 that the latest 5.3.0 build had the problem? Was a collision detection fix pushed in the past few days? I don't see anything relevant merged on GitHub.

If anything does happen again with collision, I'll ask about it, but one problem still stands.

For the record, this problem isn't related to collision detection. When placed, blocks are just popped into existence in already occupied space. Probably a problem with the code that checks if a block is allowed to be placed.

Might be worth checking in "all settings" > controls > enable_build_where_you_stand

Code: Select all

#    If enabled, you can place blocks at the position (feet + eye level) where you stand.
#    This is helpful when working with nodeboxes in small areas.

Tried looking at the settings however, I could still build inside of myself either way building up, the setting you showed me doesn't help, but thanks anyway.

Make sure you have noclip turned off as well, since that has the same effect as build_where_you_stand in regards to placing

Re: Collision

PolySaken come on, of course we have noclip disabled
we're talking about actual collision issues
not some noob mistake
we're not 5yr-olds ;)
I think I more than make that obvious myself by hacking the b3d format XD

EDIT: btw, the reason cats posted about it is because it affects him worse than me
he's bothered by things like this because he does pvp, I'm more of a creative person and just deal with it
but yes, I do experience it normally as well when jumping or releasing Shift

I don't think you can experience that with noclip enabled because you can only noclip while flying ;)

EDIT2:
plus if I must, it was mentioned before here ;)
