nice project,
how do you plan to interface a chess engine in c++ ?
using behaviors ?

yes, sorry it's "relative"

Hi tutorial doctor,

there is different schools about learning, I learned by myself mainly because I was passionate about making an adventure game when I was 16. The first thing I played with was basic on Amstrad CPC some years before, I also liked to draw. Later I discovered a software called "Clic and Play" on PC to make small games without coding. After some time only I started learning C and made a small 3d engine for ms-dos. I learned a lot by looking at code from a library called Allegro, and by trial and error.

You don't specially need to know complex syntax and hardware code to make games or softwares today, but what you definitevely need to master is logic. I'm not a hard core programmer, there is a lot of concepts I don't know and I never touched assembly.

In 3d, you need some math basics, specially vectors, with your best friends (dot product, sqrt, cross product...). Alkso learn how to use matrices and what they do (even if you don't know how it works inside).

The way I work is to think about what I want to do on paper, the structure, the logic, before switching on any computer.

I do some research to find good libraries to not write something already existing, then I focus on the general design, trying to keep things as simple as possible. I optimize only the parts that needs it, by anticipation or after profiling.

After, it's passion, curiosity,
and of course time.

(to give you an idea, Maratis it's 10 years of work plus now all the contributors time)

did you look at this exemple in the wiki ?
http://wiki.maratis3d.org/index.php?tit … ng_example

I made it to show how to create a class-like object.

Argoon :
for global sounds, you can use a stereo sound (only mono sounds are 3d)
or select the "local" option in the sound property and the sound position will be local to the camera (the global effect you want) > set the position to "0 0 0" for a centered sound

We all agree that Maratis needs more documentation,
the question is, how can we do it and what do we do first.

We cannot follow the direction of unity or udk because it's impossible, and it's not the point,
they are financed by millions of dollars every years.

We need to go step by step with a priority for the most important features,
and it can only happen with the effort of multiple people, it's not a little task.

255 just added pages of documentation in the c++ part, when I have some time I do it too,
others do, that's the way, it will take time and contributors, that's all.

aout m_type in material :

it's an optional variable from the mesh format,
right now it's not used, a material is "standard" by default and "custom" is there is a shader attached (FX).

It cannot be made enum because it's use is not defined,
for example it could be useful if you write a custom renderer where you want different types of materials that are not controlled by shaders.

Normally you can access like that :

sce = bpy.context.scene
mar_anim_list = sce.mar_anim_list

num_anims = len(mar_anim_list)

for i in range(num_anims):
    start = mar_anim_list[i].my_item.start
    end = mar_anim_list[i].my_item.end
    loops = mar_anim_list[i].my_item.loops

and to add a new animation :

mar_anim_list.add()
mar_anim_list[-1].name = "Anim%d" % (len(mar_anim_list) - 1)
mar_anim_list[-1].my_item.start = start
mar_anim_list[-1].my_item.end = end
...

can you explain more ? when you say exporter tab what do you mean ?

To be be tested but you could do that (after parenting is computed) :

MObject3d * parentBone = bone->getParent();
MVector3 P_entity = entity->getInversePosition(P); // entity space

if(parentBone)
{
    MVector3 P_parent = parentBone->getInversePosition(P_entity); // bone parent space
    bone->setPosition(P_parent);
}
else
{
     bone->setPosition(P_entity); // no parent so the bone is in entity space
}

[EDIT : modified "MObject3d * parentBone"]

setAnimationSpeed controls at what speed the animation is played,
so if you use setCurrentFrame to manually set the frame of the animation
the animation speed is useless (you don't want the animation to be played as you control it yourself).
