AI-driven Tracked Amphibious Vehicles Get Stuck in Rivers
New, NormalPublic
Actions

Description

The AI is unable to cross rivers with the Global Mobilization M113 and BMP. Seems related to the fact that both are tracked. The vehicles go into the water and then just stop. Wheeled vehicles do not have this problem.

I am unsure whether this is an engine limitation or not, because there are no vanilla amphibious tracked vehicles to use as a control experiment.

Since this issue appears to be pathfinding/engine related and not data related (as per GM devs on discord), I am filing this as a Arma 3 bug. It is an issue affecting functionality of at least one CDLC, which is officially supported 3rd party content.

In the image, note how the speed is zero although there's still some bubbles in the water as if the vehicle is moving.

Category
AI Pathfinding / Motion
Steps To Reproduce
  1. Open map with river, like Livonia.
  2. Place a crewed GM tracked vehicle near the river, does not matter where along the river.
  3. Give the vehicles a move order or editor WP about 200m on the other side.
  4. Observe behaviour.
Additional Information

This obviously breaks any sort of AI-controlled amphibious action with tracked vehicles. Tracked vehicles are already notorious for pathfinding or space-launch issues...

This happens with the AAV9 from Expeditionary Forces CDLC as well, seems like the AI is unable to use tracked vehicles in water, they can only go forward.
