Hi,
How can I make my actor to move to the closest "tree" actor?

You can use the getAllActorsInCollision to get the actors that you want to test, and use the distance function the get the smaller distance to your player.


Look more here:http://game-editor.com/docs/script_reference.htm#distance
http://game-editor.com/docs/script_refe ... ncollision
http://game-editor.com/examples/collisiongroups.zip

I'll try if I can get it work with those link. Thanks

I couldn't get it work.
Could someone make a example of the moveto closest actor?

EDIT: Happy new year!

Can someone help?
I still can't get it work...

I have an actor called monster and I would like it to move towards nearest actor called sini.
I readed all that the documentation is saying about distance and trying to understand the logic of the getAllactorsinCollision but I can't still figure how should I make it.

Can you post the code?

I haven't got any code of moveto closest actor because I can't understand the way it works. (I just tried different things but it said that there were errors in code) If there could be some kind of tutorial/demonstration or something...

Use a sensor actor (Filled Region) to act like a sensor.
Get all actors that collides with the sensor and calculate the distance.

Here is the code:

Code: Select all

int n;
double mindist = 10000; //Initialize min distance with some high value
Actor *actors, *closest = NULL;

//Get all actors that collides with the sensor actor
actors = getAllActorsInCollision("Event Actor", &n);


if(actors)
{
  int i;
  for(i = 0; i < n; i++)
  {
    if(strcmp(actors[i].name, "player") != 0) //Ignore the player actor
    {
       double d = distance(player.x, player.y, actors[i].x, actors[i].y);
       if(d < mindist)
       {
           //Hold the closest actor
           closest = (actors + i);
           mindist = d;
       }
    }
  }
}

//Move the closest actor, if any
if(closest)
{
    MoveTo(closest->clonename, 0, 0, 5, "player", "");
}

I couldn't open the example ged but I'll try that code. I haven't yet never used so complicated looking code in GE!
I write that in the filled region's draw actor?

In this sample I put in the 'Mouse Button Down' event of the sensor actor

Ok, and because my monster checks always which is the closest of my actors; I put it in the draw actor of the filled.

Sorry to distract, but how do I edit this line:

Code: Select all

MoveTo(closest->clonename, 0, 0, 5, "player", "");

What you need?

Well, I don't completely understand the code but I want to make the "player" to move towards the closest "tree" actor.

Change the line:

Code: Select all

if(strcmp(actors[i].name, "player") != 0) //Ignore the player actor

To:

Code: Select all

if(strcmp(actors[i].name, "tree") == 0) //On tree actors
