FOSS gamedev and creative worlds

honestly i don't know why this hasn't been added.
(i'm not just a noob from minecraft)
knockback would be very nice, especially for minigame servers (fish-slap that guy off the island)

i think the devs just put it off once and forgot about it.

Knockback should be done client side, and tools should be added to the knockback group if they knock the player back.

IMO anyways.

no knockback group, just a knockback value
and knockback function to knock people somewhere remotely

Why not groups? It would be simple, just add your tool to group knockback<value> and then the client can figure out how much knockback, no protocol bump.

Would the knockback group define the destination position or how exactly should this work? Troutslap someone and he'll get teleported to the prison?
Currently you can kill a player and it will get teleport to his last used bed/spawn or a random position around spawn. You could even override the item's on_use function to reach the same thing.

@krock: he is talking of the minecraft knocback: hit=you are punched back

Knockback, as in being hit backwards.
like being hit by and arrow and falling off a bridge because of knockback.

Agree, I would like a group.
Add a poll?
Edit: The corresponding armor group should define knockback resistance, as 100 being fully knocked back and no value being not knocked back at all.

+1 For default knockback, and the possibility to disable it if needed

I like the idea a bit, in some servers can be very useful!

But can be a nice idea have a specific animation for knockback too!

An animation can be done with another mod.

seems like there is already some entity knockback.

In the engine, there isn't. Not to mention that mod-applied knockback is server-side, without any client-side prediction.

no it's just weird, with mobs redo when i puch a mob sometimes he moves back a bit.

What if this was written in source code to get tool strength and multiply this into velocity to object being punched to set velocity?

Would this be as easy as it seems? It would be like punching a minecart, but for all entities like mobs, players, and things.

That's part of the mod, not the engine, and thus suffers from the caveat I mentioned in the post above.

Please don't calculate it from tool strength! A separate group gives more control and allows funny features ( like a "force push" that does not do any damage but knocks the player back)
I agree that knockback should work for all objects.

Yep, totally true. +1

^ +100

I think, maybe we can add another feature with the knockback...

The knock up!!! For combos!

Oh yeah!
And a "Force Pull" maybe?

That can work!

knockback can be set as punch value for all tools with no value. And maybe we could have a temporary "knockback calculator" mini-app thing so mod devs could calculate knockback for their existing swords based on the ratios used by default.

Knockback is in some of the mobs mods but to have it work with players the devs would need to add a missing player:set_velocity() function into the game itself.

Hmmmmmm
Wish I were a dev

Minetest Kombat 5

I would prefer an add_impulse function over set_velocity since it will feel more accurate on the client end (no issues with the velocity from get_velocity being too old because of lag)

What if someone wants to change knockback value from specific Items?
