[solved] Enemies kind of surrounding the player ?

Hi.

I'd like my enemies to have a behavior like this (sort of) :

[attachment=0:ij9t3kj4][/attachment:ij9t3kj4]

Let me know if it's not clear enough

I'm pretty sure I need some math (angles and stuff) to do this but I don't have any clue about how to do this. Plus I don't know math.

Any advice/idea ?

Give them the "Custom Movement" behavior with Set Angle towards position Player.X, Player.Y.

And you might want to combine that with:

System > Distance (Player.X, Player.Y, Enemy.X, Enemy.Y) <200

or something like it..

Hope this helps.

I managed to do exactly what I intended using two algorithms :

https://math.stackexchange.com/question ... d-distance to defines two very distant point related to the enemy's current angle

And http://devmag.org.za/2009/04/17/basic-c ... 2d-part-2/ to test the collision between a circle and the line defined by the previous two distant points.

You can try it here : http://canapin.com/construct/scarletland/01/ and use the arrows to move (and left click to shoot)

Since it may interest other people, I attach the commented .capx.

You'll also need the LiteTween behavior : behavior-litetween_t70700
