Stadium Crowd Example example file

Crowd example showing a stadium setup

Example for

Crowd Solver

Example

The setup creates a stadium crowd. The rotating cheer_bbox object is used as a bounding box for the agents. When they are inside it it will trigger a transition from a sitting to a cheering state. After a few seconds the cheering crowd sits back down by transitioning into a sitting state.

Note

The animation clips need to be baked out before playing the scene. This should happen automatically if example is created from Crowds shelf. Otherwise save scene file to a location of your choice and click Render on '/obj/bake_cycles' ropnet to write out the files. The default path for the files is ${HIP}/agents.

Tip

To only see a section of the crowd for quicker preview there’s a switch node in /obj/crowdsource/switch_all_subsection. When 0 it will show all agents, when set to 1 will only show a small section.
