Strategy Demo? Is ground made in photoshop or 3d Studio?

Wajahat Karim — GMT

I know that how 3d models have been generated using MeshUtils.generateClass(). But that works for 3ds loader. However, i couldnt understand that how ground has been generated? there are 4 spots in map, covered by Box1, Box2, BigBox1, BigBox2, which have been marked black in map ground image and buildings have been loaded on those spots. I replaced map image, but those areas are still available in my new ground?

What should I do?

I beg pardon for my poor english. Thanks for your help.....

Object3D class

TOMIYASU — GMT

Now I'm creating my 3D Flash objects by using Alternativa3D 8 successfully.
Then yestreday I came accross the script in the attached file and tried to compile it.
But compiler indicates <"Object3D" class definition can't be found>
Isn't this included in the latest libraly "Alternativa3D 8" ?
If so, how can I get the older version including class definition of "Object3D" ?

Hi to all, i'm actualy using this: http://forum.alternativaplatform.com/posts/list/2972.page#50897 to let see the downloading progress of my 3ds object
but i would like also a preload bar like a flash site, it's ok to see the parsing of the objects, but later.
Is there a way to do this?

How to properly dispose of bitmap from MovieClipMaterial

taurus76 — GMT

Hi!

I've got problems with MovieClipMaterial

When I change the material the bitmap from MovieClipMaterial remains in alt3d engine and is still used.

First i change the material to new one and then I try:
mcMaterial.texture.bitmapData.dispose();

Bu then I get errors every frame: (even when there is another material assigned to the object)

ArgumentError: Error #2015: Invalid BitmapData.
at flash.display::BitmapData/fillRect()
at alternativa.engine3d.materials::MovieClipMaterial/redraw()[G:\works\Alternativa3D\src\alternativa\engine3d\materials\MovieClipMaterial.as:111]

thx

Preloader

mastrok — GMT

hello every body.
I want to create a preloader for my swf but i have a lot of problems.
When I simply make a preloader as3, it's don't work:

////////////////////////////////////////////////////////
function onComplete(evt:Event):void {
// affichage du conteneur
addChild(conteneurImage);
}
// Progression du chargement
function onProgress(evt:ProgressEvent):void {
var p:int=(evt.bytesLoaded*100)/evt.bytesTotal;
taille.text=p+" %";
if (p>25) {
var veingt= new (Veingt);
addChild(veingt);
veingt.x=330;
veingt.y=308;
}
if (p>50) {
var cinquante= new (Cinquante);
addChild(cinquante);
cinquante.x=330;
cinquante.y=308;
}
if (p>75) {
var soixanteQuinze= new (SoixanteQuinze);

}
}

Aliasing Texture Bug

taktika — GMT

Hy everybody !

A recurrent problem with 3d is a sort of wrong "antialising" for texture. I'm not sure to have the good words, that's why i'm post some picture.

[img]http://www.disturbance.pro/test/ex_2.png[/img]

[img]http://www.disturbance.pro/test/ex_3.png[/img]

[img]http://www.disturbance.pro/test/ex_4.png[/img]

Any way to help me reduce this bad effect...? One solution is to had a second layer under a plane, but my cpu don't like this !
I understand that sometime between 2 surfaces we have a little bug, but i don't understand why some lines appaer on a plane surface (plane is from a 3DS object).

:mrgreen:

I try some config with "loader.precision = TextureMaterialPrecision.HIGH" but no effect.

problem with radiusZ property

fermmm — GMT

It seems that it's not possible to change the radiusZ property of a collider in any moment.
I need to make the controller to crunch, with control key, to fit in smaller places or not, so i added this function to the control key in the bunker example:
[code]
private function set crouchMode(value:Boolean):void {
if (value) {
controller.collider.radiusZ = 48
}else {
controller.collider.radiusZ = 38
}
}
[/code]
That is the only thing i've changed in the bunker example.
The problem is when controller.collider.radiusZ is 38 and i press W to walk, the screen turns white forever. I try to look arund but i see nothing, so i can't know if i'm out of the map or what happens, and doesn't trow any error. A textarea i use to see variables becomes invisible (it has a black font).
I've tried with different values, but the same happens.
Can somebody explain me whats happening or if that's not the way to make a crouch effect? thanks.

Reflection / Mirror effect

taktika — GMT

Hy everybody !

Im' currently search some ideas to create a reflection effect. I wan't to creat a mirror, or just a nice glass effect.
I have read that maybe reflection is going to be integrate (post from 2 years) but i find nothing about it ...

In this example, we can find a simple mirror effect : http://wineperm.ru/

So what is the best way? Create some parallel 3D scene just for the effect ? I think my CPU doesn't like this way... 8)

Need better visibility control than addChild/removeChild

Joe — GMT

I built a FLAR application that has 10 3ds models in it with corresponding AR markers. Basically when a marker is found its corresponding model is added (addChild()), and removed (removeChild()) when its marker is removed. The addChild event freezes the app for a second as the BSP has to reprocesses and rebuild. I need a better solution quick! What could be a better solution? Something like a visible property or even something like parent.hideChild( child )

Any ideas? Maybe move object behind camera when it needs to be hidden??

Preparing 3d-models for Alternativa3D

pinilevi — GMT

I create a 3ds file and when I tray to loading it I get an error
"TypeError: Error #1009: Cannot access a property or method of a null object reference."

but when I take 3ds file from the Internet or from your examples every thing works great,
Do I need to export the file in a particular or specific settings?

Slanted surface movement

marind — GMT

In Tanki Online, the tanks move and rotate in relation to the surface they are on. They tilt backwards when climbing a ramp for example. My question is, can I achieve this same effect using the current release of the engine or is that something that can only be done with the next generation engine?

Collision Event Handling

marind — GMT

Hi,

I am making a car game. I was wondering if there is any way to detect a collision with an object that causes some other action to occur. For example, if you drive a car over a specific area, like a square on the floor, that square turns green. Please help! :)

What is the benefit of using generateClass over LoaderOBJ or Loader3DS?

marind — GMT

Hi,

I noticed in the "Flat" demo, you guys used generateClass() to make the model of the building.

My question is, what is the benefit (if any) to using generateClass() as opposed to loading the OBJ or 3DS model using LoaderOBJ and Loader3DS? Does the generateClass() improve rendering performance and/or load time?

Thanks!

Movement smoothing

emuse — GMT

How can movement / mouse-smoothing be done?

E.g. If you compare this http://www.infiniteturtles.co.uk/projects/away3d/demos/hacienda/BSPImportTest.html
with the bunker or flat demo, than the movement is a lot smoother.

I like the “direct-response” movement of alternativa, but it doesnt hide the glitches or brusk changes. So I would like to see a little bit of smoothing in Alternativa to make it look more fluent, how can I do that?

Best regards

How to force the rendering of the view associated to a specific camera

flocquet — GMT

I have 2 cameras in the scene, and I am trying to force the rendering of the view for only one of the 2 cameras (which is not associated to the viewport displayed on screen), without any animation in the scene (even of the observer).
I have noticed that moving the camera makes it renders its view, but I don't want to make it move in order to refresh my associated view. Is there any method on the camera or view classes to make it happen (for example some 'dirty' flag)? Thanks for your help !

Problem with TextureMaterial

taurus76 — GMT

Hi!

I've got problem with TextureMaterial. I'm using Flash CS4.

I draw my planes with createVertex, createFace, createSurface. While applying FillMaterial or WireMaterial everything works ok, but when I try to use TextureMaterial i get pink/black checkerboard. When I apply this material to regular plane, it works OK.

my code:
[code]
var bd:BitmapData = new BitmapData(100, 100, true, 0x000000);
bd.noise(123, 123);
var texture:Texture = new Texture(bd);
var textmat = new TextureMaterial(texture, 1, true, true);
moveAllFacesToSurface("surface1");
setMaterialToSurface(textmat, "surface1");
[/code]

FPS drops when objects move. What am i doing wrong ?

rr404 — GMT

Hi,

swf and sources of my test here :

SWF : http://cut3.free.fr/alternativa3d/test002_main.html

SRC : http://cut3.free.fr/alternativa3d/src

# What this final test exemple do:

- I have a grid of cubes : 4x5 built at the initialisation of scene.
- The first 3 rows move according to a cosinus the last one stays still. (so far 15->20fps :( )
- I set increasing mobility to my objects at init according to their position (more@ back=> more mobility) and the still line has mobility = 0 (increase of fps to 23) // i know here i'm not using it optimaly but i see what it's suposed to do
- I display the bps tree to check what moves

[color=red][b]# Questions:[/b]
¤ Do i HAVE to set mobility to allow such a scene to run smoothly ? (i'm expecting a 100fps for such an easy exemple)
-> What am i doing wrong there ?
-> Is there an automatic way to do this ?

¤ Can i Freeze the redrawing order ? If i know that the line at the back will always be at the back and so on.
[/color]

# (history) My Tests and problems :

I did a simple test scene filled with a few cubes that move according to a cosinus at every frame.

I first tried with a grid of 10x10 moving cubes and i was stuned to see a [b]0.1fps[/b]. I was expecting some fps drop with the z order resolution but it was a bit heavy there.

I had only 10 cubes moving but still with the other 90 other (not moving) in the scene... [b]2fps[/b] ...

So i look up here and there, found out about [b]Object3d.mobility[/b] and tried some trick (as you can see in my sources) but still no good result.

I've tried the same on other engine and it works fine with 10x10 moving cubes.

[b]As I still believe Alternativa is the overall best flash 3d engine I'm turning to the answer : "I'm f***ng up somewhere in my code".. but where?[/b]

Making things simple...

xon — GMT

Hi,
I was wondering if there's a way of simply loading a 3D model and textures (with a XML file or something like that for file names) without programming in flash? I have only basic knowledge in flash...
thanks!

Post-effects / filters

emuse — GMT

Hello,

Does anyone have examples of how post-effects(filters) are applied? We are trying to create a HDR-bloom effect, but don’t know where to hook it on to the engine.

Best regards,

general questions

mab11 — GMT

hi!

Are the following features supported by Alternativa3D:

backface culling?
occlusion culling?
fog?
bitmap tiling?
environment mapping (in the current version)?

Are there beside BSP-trees any other Z-sorting algorithms?

thanks!

Sprite Clipping Issue

binalogue — GMT

I've got an environment where I need a bunch of trees. Due to polygon reasons, I have opted for planes textured with SpriteTextureMaterial to keep polycount low. I am loading .3DS and mapping various TextureMaterials based on object names to obtain tree variety. Everything is working fine, execpt for the trunks of the trees are being cropped out. This looks like a clipping issue to me. Any tips/tricks/suggetions for how to improve this? My client is currently in the process of purchasing a standard license from you before we go live.

what about the A3D's 3d model?

dreamerflyer — GMT

I'm learning A3D'S 3d model,and find most of them are made by codes,Exampl:
newMesh=new Mesh();

newMesh.createVertex( 290.00, 375.00, -25.00, 0);
newMesh.createVertex( 270.00, 384.00, -25.00, 1);
newMesh.createVertex(-270.00, 384.00, -25.00, 2);
newMesh.createVertex(-290.00, 375.00, -25.00, 3);
....................................
I .m confused about this,Are them made by codes manually?Or There is the tool to transfor other format 's model to A3D'S model?
If youn know,pls tell me,thanks!
