Bug/help in move to action

[Freddy]

I think there is a bug in the draw actor -> move_to function. When you use another event such as keydown, the move to works fine, but with draw actor, the actor that needs to move stays still, at least when there are obsticales. Is there a way that I can have an actor move to another actor, and dodge obsticales? Here is a screenshot to help explain. The red dot represents a zombie. The blue dot represents you. I want the red dot to move towards the blue dot, while avoiding the buildings. And of course the player would be moving around too, so it would be nice if the zombie could keep renewing the targeted location. Please reply if there is a way to do this, it is crucial to my new game.

There are two move-to functions. one is for draw, and the other is to move actors. You want to use MoveTo and not moveto

[Freddy]

Yes, I did that, but if you put obsticales in the way, it wont move at all.

[Fuzzy]

Oh I see. you are looking for path-finding. Google A* and or pathfinding. its been done to death. Lots of information out there

[DilloDude]

Does the avoid with MoveTo work properly when used with another event?

[makslane]

The avoid option of the Move To action uses the A* algorithm.
The action calculates the path only when is called. If you want to update the path, you can call the Move To action in a Draw Actor event.

I already made the draw actor MoveTo event, but when I made it avoid an obsticale, it would not move. I have a question about the A* for Fuzzy though: How on earth am I supposed to apply the concept to GE? I also dont get a word of it, but I only made one search, so I will keep trying .

I got another question.
can u also make an actor avoid others without moving to something?
for example: I got a spaceship an asteroids are flying towards it and it has to avoid them automatically.
how?

Ship>DrawActor>ScriptEditor>

Code: Select all

if(y==asteroid.y+25) //if the asteroids are moving down
{
    avoid=rand(10);
    if(avoid<5)
    {
         x=x+5;
    }
    if(avoid>5)
    {
         x=x-5;
    }
}

maybe it could works...

[Kalladdolf]

There's actually a function called "avoid"?
Why didn't I see it???
and in your code it seems like avoid is horizontal...

[Bee-Ant]

No, it's an actor variable...
Uh huh...

[Kalladdolf]

AH, I get what u mean!
that's too easy!
why didn't I think of that?
*sniff*
buhuuuuuuuuuuu!
do you know where ma brains is?

[Bee-Ant]

In your knee nonono...don't hear me

[Kalladdolf]
