Marbles bouncing on a speaker

Hello Forum,

I am trying to get an animation going where some marbles fall onto a speaker. The speaker is vibrating (I have already baked its position to f curves) however when I go to the game engine and hit play, the speaker disappears and my marbles fall into the abyss. And if I go to render mode and play my scene (on the timeline) the music plays, the speaker vibrates but the marbles stay in the air. I have also recorded the animation of the marbles falling but they just fall through the speaker (as the speaker isnt there when I press ā€œPā€). Is there a way to make the marbles fall and then bounce around, reacting to the vibration of the speaker?

Any help is very very much appreciated! Thanks :slight_smile:

You need to set up logic bricks in the game engine to play the movement of your speaker. Then press P and record the movement of your marbles. You should also match the frame rate in game render and blender render. Here is a rough example.
