Re: Trying to implement a rope, but it freeze

I'm now sure @drleviathan is right.

When move the kinematic object, dyamic objects connected to it via some kind of constraint pivot would not be activated.

They need to be manually activated.

Re: Trying to implement a rope, but it freeze

Thanks for telling me the activition theory! I guess I would rewrite the code. I see the manual said the kinematic obj needed to be marked, otherwise they would be static obj which should not be moved. Those length calculations are not considered carefully either, might be some "pivot inside an obje...

Trying to implement a rope, but it freeze

Greetings. I'm trying to implement a rope. I'm using a simplified model: a kinematic obj on the top <- a P2P constraint <- a mass obj in the middle <- a P2P constraint <- a tail obj to connect payload So I wrote this typedef struct { btRigidBody* body; GLfloat size; } draw_box; //for OpenGL. //thing...
