Nice,
thank you for sharing !

There is a topic about Maratis iPhone publishing :
http://forum.maratis3d.com/viewtopic.php?id=66

An in-progress iPhone xcode project can be found on svn :
http://code.google.com/p/maratis/source … Publishing

Timer, Timeline:

The lua script update is syncronised at 60fps,
so you can create a timer with a simple variable like that :

t = 0

function onSceneUpdate()

    -- 1 second
    if t == 60  then
        print("one second")
    end

    t = t+1
end

Non-bones blender animation :

The actual blender python script is not implementing it,
that's possible in the future, if a contributor can improve the python script
it would be nice.

Animation Blending :

Currently not, I made some code for morphing, but I'm not sure I finished it, laking of time.
I will try to have a look at it at some point.

You can find the current xcode project in SVN branches/iPhonePublishing/ :

yes, i didn't find the time to continue since this post, so it's still missing the sound and the touch input, but if you don't mind testing the in-progress version, I will post it tomorrow.

I will watch to correct the full example, but for now you can try this :

vec3 N = normalize(normal);

float ink = dot(normalize(-position), N);
ink = clamp(pow(ink*3.0, 20.0), 0.0, 1.0);

gl_FragColor = vec4(ink, ink, ink, 1.0);

are you using very large triangles ?
it's possible that bullet physics need subdivide surface when it's large.

Hi, nice

I release a new example with envmap shaders if you want to have a look :
http://www.maratis3d.org/?p=548

Hi,
for the tree, for hard transparency,
your foliage texture just need to have an alpha component
using pnj format for example.

The yo-frankie demo is using transparency for trees, i included the blend files
if you want to compare with your tree.

Look in the console window of Maratis if some error is printed.
If you want a shader example there is one in there : "Example/Demos/shaders/"

I'll try to send a tested reflexion shader soon.

Hi,

Animated gifs:
They are not supported, if you want to use animated textures, you'll have to make a single texture strip including multiple images, then animate texture translate to decal your texture in time.

Bullets:
There is a way to do it by script, but I should say that it will be more easy and optimized to use a c++ game plugin.
Look at Maratis/Examples/Demos/scripts/follow.lua to have a look on a more complex lua script to move objects.
Later, I'll try to give you a better example.

About shaders :
Create a custom shader will be the best to have your reflexion effect, in this case, as Kralle suggested, an envmap will be good enough.

A spherical envmap like this one for example :

You can link shader using Maratis Blender export :

You can access each texture slot with your custom shader

To create shaders, you can just use a text editor, as Maratis is updating assets in realtime, each time you will modify and save your shader, the result will automatically appear on Maratis.

To create a reflexion using a shader, you can use the normals as uv coord, something like :

VERTEX SHADER:

attribute vec3 Vertex;
attribute vec3 Normal;

uniform mat4 ModelViewMatrix;
uniform mat4 ProjModelViewMatrix;
uniform mat4 NormalMatrix;

varying vec3 position, normal;

void main(void)
{
    normal = (NormalMatrix * vec4(Normal, 1.0)).xyz;
    position = (ModelViewMatrix * vec4(Vertex, 1.0)).xyz;
    gl_Position = ProjModelViewMatrix * vec4(Vertex, 1.0);
}

FRAGMENT SHADER:

uniform sampler2D Texture[8];
varying vec3 position, normal;

void main(void)
{
    vec3 N = normalize(normal);
    vec4 reflection = texture2D(Texture[0], N.xy);
    gl_FragColor = reflection;
}

This example is only showing how to make an envmap, for a full shader including texture, diffuse, normal map, you can have a look to the standard Maratis shaders, located in the source distribution : Maratis/Common/MRenderers/MStandardShaders.h

When I'll have some time, I'll try to give a standard shader that can be used as a start.

The collision test is returning true when there is a collision, so since you objects are in collision you send a "playSound" order and the sound play from the beginning.

In script, you should do something like :

collision = 0

function onSceneUpdate()

    if isCollisionBetween(A, B) then
        if collision == 0 then
            playSound(sound)
        end
        collision = 1
    else
        collision = 0
    end

end
