Using the entityVelocity channel

If the Locomotion Behavior is not reacting as you want, or if you need more control, you can use a the entityVelocity Channel to control a network of Motion Behaviors.

Let's see how we can start a behavior only if the velocity magnitude is greater than 0.5:

  • Double-Click on the Start Trigger in the Behavior Editor
  • Add an Expression Trigger 
  • Right-click on it, as choose "set as root"
  • In the attribute editor
    • Enter this.entityVelocity in the expression field
    • Set the wanted operator
    • Enter the value to which you want to compare the speed of your character (beware of units)

 

Note: because at simulation init values can be strange, it may sometimes help to protect the trigger with a Frame Trigger, so that the entityVelocity trigger is only activated once the simulation values are stabilized

You can use this with multiple motions in parrallel with different start/stop conditions, in order to play the walk, run, idle motion based on the particle speed.
