  • I am currently using pathfinding to have objects navigate a course. On path found the objects all move. I'd like a simple way to get them to only start the movement once all objects on the screen have found the path. (Rather than staggered starts as each object finds its path slightly after the one before)

  • Add a boolean instance variable "pathIsFound" to this object. Add this event: 

    Object On Path Found -> Object set pathIsFound to true

 System Pick all Object

 Object boolean pathIsFound is set
 ..System compare two values: Object.Count=Object.PickedCount -> Object move along path

    thanks for the reply. I gave this a try and there is still a little lag between each sprite moving.

    The other issue I have found is that if I do pathfound = move along path it can pick up obstacles blocking the route. If I try and set a variable first it 'forgets' there are obstacles added to the path.

  • Can you post your capx, or a screenshot of the event sheet?

    Hopefully that should work for you (To download)

    I remade this and having trouble getting your way to work at all now

    This works (edit deleted original Pick all event, wasn't needed) , just double checked, and they start at very nearly all the same time, and find path.

    System | Compare Two Values | ai.PickedCount = ai.Count

    side note on your capx, you are better off using 3 individual sprites for the obstacles, as this will be much more efficient than a large image with lots of collision points.

  • Yeah, "pick all" event should should be nested under "path found" event, as it's done on sizcoz's screenshot above. I tried to show it in my first comment, but the new forum kills code formatting...

    Thanks both :) The nesting was the problem. All working now many thanks!!!
