GMF Queries

[G.K.]

I'm finishing the new arena I'm making for my next tournament, but I have a series of questions that surpass my current expertise with GMFs, an I was wondering if people could lend a hand with my questions.

Firstly, to merge two GMF's (Here an object with the main arena), do I just cut/paste the various sections from one to the other, and change the object number and texture ID's?

[JoeBlo]

yes essentially you place all of the indented section for that object in the objects list and raise the count by 1

Then you have to put the texture stuff in, you will likely have to change the texture numbers so it doesn't conflict

Then rigidbody stuff if you want (thats optional)

[G.K.]

Right, problem - I did so, but when it came to compiling, I got this error:



The arena works mostly, but the object I was trying to put in isn't there and the floor has lost its bitmap texture.

[JoeBlo]

You have done the Ridgidbody section all wrong..

Make sure it fits within all the same indentations as other single objects

Is the node name the same in every occurrence too?

[G.K.]

I failed to notice the *COUNT number before, which I've now upped, could that be the cause of the problems?

Node names are all the same.

[G.K.]

DP: That fixed the issue, the arena works, but both textures have somehow combined onto the new object and the floor is still textureless.

New error messages:

[JoeBlo]

did you give it a unique texture number like I mention the my first post ?

[G.K.]

Yes, but I found that problem, I think - I had both textures under the second object's material.

Now I've got it working, should I repeat for further objects?

[JoeBlo]

if it works then yep

Indenting is the biggest pain with GMF's..

[G.K.]

Next, I don't understand collision lines. Is there a guide for how they can correspond to TMROWS?

Also, what is the point of NPOV's?

And how would one lighten an object's texture via the GMF, if it is at all possible?

[Clickbeetle]

Collision lines and TM_Rows are two completely different things.
 
Collision lines are invisible lines you set in the .py.  They're just numbers; they have no shape.  Here's the collision lines for Lu-Tze's RA2 tournament arena:
 
        self.AddCollisionLine((-9.22, -11.62 ), (-9.22, 11.62 ))
        self.AddCollisionLine((-9.22, 11.62 ), (9.22, 11.62 ))
        self.AddCollisionLine((9.22, 11.62 ), (9.22, -11.62 ))
        self.AddCollisionLine((9.22, -11.62 ), (-9.22, -11.62 ))
 
Pretty simple.  The first set of numbers is the start point and the second set is the end point.  The AI will avoid the invisible line between those two points.  Note that the collision line extends infinitely up and down so there is no height coordinate.  The numbers use the same coordinate grid as the objects in the arena.  So if your floor object is at point 0, 0, 0, you can just set the collision lines to the same coordinates as the floor vertexes.
 
Put the collision lines in def Activate in the .py.
 
POV's are a set of paths the AI uses to navigate around obstacles.  You only need them if you have an arena like the BBEANS arena with a blade in the middle.  Without POV's, the AI won't know how to get around the blade.
 
And there's no way I can think of to lighten textures in the gmf.  Well no practical way anyway... I suppose you could add a white reflection map.  But that would require another texture which would defeat the purpose.

[G.K.]

Thank you very much.

[G.K.]

BUMP:

Do I need POV's and collision lines for a centre object?

[Trovaner]

If you want the AI to navigate well within your arena, you'll want POV's and collision lines whenever there is an unmovable obstruction that could get between the bots.

POV's are good for mapping AI routes around obstacles or hazards.
Collision lines are good for keeping the AI away from things (pits, walls, hazards, etc.).

[G.K.]

But POV's are unecessary for the walls?

[Trovaner]

For the most part, the AI always moves towards its opponent so there would be no point in adding POV's for walls unless it was possible for the wall to come between the bots.

[G.K.]

Thanks.

Also, regarding POV's, I'm probably being an idiot but I've confused myself again.

A while back, Trov explained  them to me and said this:

#self.AddPOV(POV_ID,X-Coordinate,Z-Coordinate,POV_ID)

I look at the BBEANS arena, and its POV's don't seem to correspond to that:

EG:

self.AddPOV(3, (-5, 5), (3, 2))

How is (-5,5) the X co-ordinate?

Or is (-5,5) the two co-ordinates, and (3,2) something indicating ID 3 joins with ID 2?

[G.K.]

DP:

I acted under those assummptions and added the POV's, however they don't seem to have worked. Bots still crash into the hazard in the middle.

Any suggestions as to where I slipped up?

[Clickbeetle]

I don't know how big your center obstacle is, but I'm guessing it's bigger than 2x2 meters.  That's where you went wrong.  The POV's don't define the edges of the hazard (collision lines do that), they define the path the AI should take around the hazard--therefore, the POV square should be bigger than the collision line square, or else the AI will hit the hazard before they try to drive around it.  Depending on the size of your hazard a cushion of 1-3 meters should be sufficient.

[G.K.]

Thanks.
