small code in C++ and motion of shifter

Hello, sirnoname and other :hi:

Thank you for yours softwares. :thbup:


I want make a source code small in C++ for be to utilised in matlab. Because there is much of possibilitie for motion control on matlab, and especially mathematically.

I have begin this with help of site, I succeed to read the effet send by Yoda in export liste, but I not come read :



current gear
current speed
gear shakee effect
accelaration speed
lateral force
vertical force
longitudinal force
pitch
yaw
roll
...

which should this found in position 20,21,22,23,24,25,...
I think this a problem of initialisation, because I have on Yoda write free buffer 35. Ever, 19 but i don't recall how I do, and if this is good?

And I want know how recovers gauge data

Thank you for yours softwares again and your help.

Re: I want make a source code small in C++

Thank you.
I will serve MMF and GetPluginDataEx for GTR2 , it will better match for me, I think.
I will keep you up-to-date of my advanced.

Re: I want make a source code small in C++

Thank you,
It's OK, I succeed to read the effet send by GTREvo directly, with your plugin

Thank you again sirnoname ,
I will keep you up-to-date of my advanced with matlab.

Re: I want make a source code small in C++

Hello

Pour les nombreux français qui vienne sur ce site et qui on seulement des notions de c++ comme moi, si vous voulez faire un petit programme en C++, il faut d'abord comprendre a quoi sert un DLL, (je ne le savait pas : ) Apres une fois que vous savez que en gros, c'est des bibliothèques de fonction qu'on peu appeler par plusieurs programme, d'où l'intérêt quelles ne soit pas en plusieurs exemplaire sur le même PC et sa évite de faire plusieur fois le boulot :thbup: .

Apres sa parerait plus évident quand on voit des plugins Race07Plugin.dll qui se promène :yippiee:

Il suffit alors de modifier un petit prog qui appel le DLL et la fonction voulu
je me suis servie du programme de Martin Wiedenbauer (thank you ;D ) qui appelai le buffer.dll

exemple a améliorer :? ( il y des truc qui doivent pas servir)

Re: I want make a source code small in C++

Hi, S-Function for Simulink has been built, but I want make a gear shifter, with pulse, which depend of car in the game (rpm,G-effect,clutch...). I think make this with a Joystick but it is not very good. I want probably use electrical motot for this.


I can send the S-Function if this interest you.

http://www.youtube.com/user/arakiriii#p ... o3HWpykPD0


Regard Akina,

Re: I want make a source code small in C++

Hi I want make this http://www.youtube.com/watch?v=bnc4IDwojPY but with the vibration and movement in function of car acceleration.

The Joystick is not good for this, not so fast for the good vibration. I want make the gear with the metal (normal) and add two motor or small acuetor for the immersive motion. Or it is possible of add a bass bump for the vibration?

The S-function has in input the game name and in output (speed,rpm,acceleration,fuel,lap...)

Re: I want make a source code small in C++

Thank you,
For the vibration i have try with simulink and basic function include by default, thus i can juste change the mean force, for example
(FFB= constant+sin(x*t) ).

You think, I can use a specifique function for vibrations (by a DLL may be) ??? It is better if the vibration signal don't cross the USB each time, just the frequency and the amplitude. :thbup:

I try of make the vibration because I had a old car and the gearbox had lot of vibration, and it moved when I accelerated , break, turn...
I like this, it is more imersive i think.

Now the Shifter is very stable,(especially for the German car ;D ), but there is a litle vibration, especially in a sport car i think.

Else for FFShifter, I think it is free ware but no open source, you can download here http://rs34.rapidshare.com/files/942782 ... ta_0_3.zip

Bye , good christmas day :

Re: I want make a source code small in C++

Ok thank you I will see this. I'm not sure of use a joystick because the appearance is not nice for a shifter. I prefer a robuste shifter in metal for the H and add a effect with small actuator(or electromagnet of big electrical relay). But I will use probably the electronic circuit of joystick.

Hello , I give the code of S-function for NSR1 by exemple
