i cant seem to get env_obj_joint to work... : / i even looked in a few mp mods (by hampa) for a solution to my problem but found nothing. can anyone help? heres an example of what i was doing.

env_obj_joint 2 2 3
pos 1.125 -5.75 7.0625

(i assume that means 2nd joint, connecting objects 2 and 3 at position x, y, z)

I can see nothing faulty with that... Do you even have a objest 2 and 3? ( stupid question, I know ) I really don't know what the problem is, maybe you could send like culapou or someone else who knows a lot about modding pm with your mod.

Recheck the X, Y and Z positions.

Moved to support.

how do u work with mod creating without numpad?

When starting worldbuilder, press K.
Press h and look at the keys inside the [ ] for non-numpad keys.

I press the ~ to create an object but nothing appears...

You might have a different keyboard than the maker of the Worldbuilder.
I'm too tired to search for a picture of the differences between his and some other keyboards, so... Just find out yourself, kay?

i did, with worldbuilder. :/
