Add the Opportunity to debug the Bullet Physics visually

Requested by @MJ-meo-dmt - At the moment you only can view the wireframe of the collision shape of the entity - more modes to be implemented.

Warning: The extra wireframes are hurting the performance badly...

How can one color single lines in a line mesh with many lines? is there a way to do this? maybe using Vertex Colors? (I've tried this - but didn't work so hints would be appreciated :))

Yea, you need to use vertex colors. There's a flag in Mesh called useVertexColors that you need to set to true as well as provide color info for each vertex.

Hey, welcome back ;-)
oh.. well I tried that earlier as I stated but found the issue now I forgot the alpha:

    lineMesh->getMesh()->addVertex(from.getX(), from.getY(), from.getZ());
    lineMesh->getMesh()->vertexColorArray.data.push_back(color.getX());
    lineMesh->getMesh()->vertexColorArray.data.push_back(color.getY());
    lineMesh->getMesh()->vertexColorArray.data.push_back(color.getZ());
    lineMesh->getMesh()->vertexColorArray.data.push_back(1.0);
