Process organize some activities flow. Why this activities cannot be THE actions created in the game? I need to pass variables to this activities rewards like I already do in actions.

Currently, tasks in a process cannot have variables like Actions do.

You can simulate a process by creating actions with dependancy chain (Action B (depends on) Action A... and so on)

I have a task system that requires an approval flow, ie. Player A creates a task, Player B accepts tasks, Player B completes task, then Player A approves and rewards.

However, when Player A creates a task, they get to define how many points should be allocated to the task, which as you mentioned, is not supported in Playlyfe Processes.

Is there a workaround to set this up with Playlyfe? (I'm comfortable with code)
