When I detach of flying vehicle, I fall.

Hi.

The first thing, your mod is awesome, it is as I dreamed when playing to m$-minecraft five years ago, I wanted build a vehicles with the cubes and I wanted that they moved.

Well, I return to the bug. When I detach of flying vehicle, I fall. It is as the vehicle has all cubes as "ghosts", the only solid cube is the meshnode controler.

Thanks, regards.

l assume it happens because collision detection in minetest doesn't work on moving objects.

No, the flying machine was stopped.

Thanks.

@HybridDog is correct, attached objects have no collision detection so there is nothing I can do unless changes are made to minetest engine. The best I can suggest is that you 'restore' your model to nodes before moving away from the controller.

c6ef2fb should help make sure the player does not fall through the controller node after detaching. It's a hack but that's how the MTG boats mod gets around it.

At first I'm able to stand on attached mesh nodes. But after playing for a while, especially when I move about 200 away from the center of the world, I can't stand on them anymore. Just the controller block. Not even moving back from where the effect first became noticeable fixes it. :(

Afaik, the attached objects should never be able to support the player, unless you mean before activation while the scaffolding/highlight nodes are still present. Either way there is nothing in the mod I am aware that could cause this so perhaps an engine issue?

[JustinLaw64]

If you create a meshnode structure near 0,0,0 and then activate it, you can actually stand on the entity nodes attached. I had no idea that the entity nodes weren't supposed to support a player.

I think it's pretty cool for that to happen! I just wish it either worked everywhere or not at all.

[stujones11]

Well it's not that they aren't supposed to support the player, it would be great if they did but as pointed out by @HybridDog attached entities do not currently support collision detection. Why this happens around 0,0,0 is a mystery to me but I'm sure there will be a logical explanation. :)
