Drive a module parameter
First set up your scene following one of the previous tutorials (make sure your agent group has a state machine module and the state is set to 1), then create an Atoms blueprint asset as described here.
- Double click on the blueprint asset
- Create an init frame override as described here.
- Right click on the viewport and disable "Context sensitive" in the menu.
- Search for "Get Behaviour module" and create a node of that type.
- Search for "Set Module Property as Int" and create a node of that type.
- Connect the nodes as shown in the picture on the right.
- Set the name of the name parameter of the "Get Behaviour module" node to "StateMachine_Behaviour" (this actually depends on the name of your state machine module).
- In the "Set Module Property as Int" node, set the "property name" to "state" and change the "value" to "0".
- Save and compile the blueprint.
- Close the window, then select the agent group from the world outliner.
- Drag and drop the blueprint asset under the other components of the agent group.
- Press play, your agents will be playing state 0.
Changing agent metadatas
First set up your scene following one of the previous tutorials (make sure your agent group has a state machine module and the state is set to 1), then create an Atoms blueprint asset as described here.
- Double click on the blueprint asset
- Create an init frame override as described here.
- Right click on the viewport and disable "Context sensitive" in the menu.
- Reproduce the graph that you see on the right. There are some special Atoms nodes you will need to use: "Get Vector 3Metadata" (gets a vector3 metadata from each agent) and "Set Vector 3Metadata" (sets a vector3 metadata on each agent)
- Save and compile the blueprint.
- Close the window, then select the agent group from the world outliner.
- Drag and drop the blueprint asset under the other components of the agent group.
- Press play, your agents will follow the player pawn during the simulation.
