Agents can be generated via Blueprint within an Atoms Crowd Blueprint Behaviour Component.
To create one, right click on the content then click on “Blueprint Class“ and the window that will popup expand “All Classes“.
At this point you can type “Behaviour” and select “Bleuprint_BehaviourComponent“.
You can add agents in one of the stages of the simulation with the InitializeNewAgent Blueprint node. Typically you would add agents in the “initSimulation“ or “initFrame“ stages.
