    Hello guys,

    I am currently making a mobile game and i came across some big frame drops. These performance drops are caused by the navmesh + navmeshagents. Currently I need to have around 150 navmesh agents at the same time in a single map. This gives me big frame drop in performance.

    I am already using lowest obstacle avoidance quality.

    Are there more ways to improve the performance of the navmesh/navmeshagents or do i need to use another library to get it running?

    For example, how games like Clash of Clans have their navigation system up and running?

    Thanks,

    Ilija

    The calculations of 100 agent's is around 20ms on a One plus one. This is ofcourse far to high. Are there any ways or techniques to get it faster?

    stagger your calls to SetDestination
    lower or switch off collision avoidance
    bake nav mesh with a coarser precision
    CoC use grid nav with a very coarse grid and I think pre determine destination of each unit to avoid overlap
