How do I make an object chase closer object

  • lets say,

    there are objects:

    1. ob1

    2. ob2

    condition:

    • there are many ob2s on the screen.
    • only one ob1 is on the screen

    Question:

    1. how do i make ob1 chase an ob2 that is closer to itself?

    2. how do i make ob1 rotate toward a closer ob2 relative to itself?

    thanks!

  • You have a pick condition sprite > pick nearest. This picks the nearest sprite to a position.

    So in one event you can combine the conditions:

    Pick all ob1

    pick nearest ob2 to x=ob1.x y=ob1.y

    Now you have ob1 & the right ob2 picked, run actions to them as you like.

  • First you need to pick the closest object using the pick nearest/furthest condition inside ob2

    condition in ob2:

    Pick nearest: X: ob1.X Y: ob1.Y

    Then rotate and move ob1 using these actions. I have showed two different ways of doing this on both actions.

    action: Rotate ob1 towards position (X: ob2.X Y: ob2.Y) or Set ob1 angle (angle(ob1.x,ob1.y,ob2.x,ob2.y))

    action: Move at angle: (self.angle) or Move at angle: (angle(ob1.x,ob1.y,ob2.x,ob2.y))
