How would I have a crowd transition have multiple output states?

I want them to transition from input state: run to output state: attack, attack_1 etc... Do i do this with vex, if so what would that code be?

I want a battle scene where when agents reach a point they begin to randomly cycle through their attack states.

It depends on the workflow you want, but you don't necessarily need to have a separate state for each clip. E.g. if you turn on the Randomize Clips option on the Crowd State DOP, agents can randomly choose a clip from the distribution you specify, and then you only have one state to manage
