I’d like to apply a force on only one vertex of a mesh.
The object of course is dynamic with rigid body (no gravity in my scene but this doesn’t matter).
Imagine you have the mesh, you attach a string to one vertex and start pulling the string. This is the effect I want to get.
The problem is setForce (via py or actuator) apply on the object center. I want to be able to choose where to apply it.
I have considered converting my force on a vertex into a force and a torque on the center of gravity of the mesh.
But the object center isn’t necesarly the center of gravity.
When there is a collision between rigid bodys or friction on one body, the GE has to apply forces not in the object center. Maybe there is something that could be re-used.
I hope to have been clear enougth…
Note: if the force was to be applied on a face instead of a vertex it would be good too.
Thanks for help.
