Anim.people set speed and set simulation time to reach a goal

Problem:

I’m working on a Python simulation where I’m controlling a character’s movement towards a target position. Here is the relevant part of my code:

character_graph.set_variable("Action", "Walk")
character_graph.set_variable("PathPoints", [carb.Float3(current_position), carb.Float3(target_position)])
character_graph.set_variable("Walk", speed)

However, I’m unclear about the exact role and impact of the speed variable, especially in relation to the simulation’s time-step (dt).

What I Want to Achieve:

  • My simulation starts with a time-step of dt = 1/100.
  • I need to set the character’s walking speed so that they reach the target position within a specific duration.
  • Specifically, I want the character to reach the target position after exactly 1/10 seconds.
  • Once the character reaches this position, I plan to set a new goal position and adjust the speed for the next period.

Specific Questions:

  1. How should the speed variable be defined to ensure the character reaches the target position within the desired time frame of 1/10 seconds? What calculations or adjustments should be made to the code?
  2. How can I correctly relate the speed variable to the physics simulation time-step (dt) ?
  3. Are there any other parts of the code or the simulation setup that I need to modify or consider?

Did you continue with that work? I’m also interested in dynamically changing the goal or walking speed of the animated people.

Currently, the anim.people release does not allow us to adjust walking speed. In a future release after the next one, we will switch to a new animation system that will enable this feature.
