IPhysics - Newton/Irrlicht framework

Miik3h · Post by **Miik3h** » Sun Jan 28, 2007 1:30 am

Now I am confused who is releasing the 'official' release?

RapchikProgrammer or Nick_Japan?

Or is it a collaboration now and you are both releasing official releases??

Either way, keep up the good work.

I and nick_japan have contacted via pm, and he has now gave me all the rights to iphysics and allowed me to call it my project but ofcourse to mention that iphysics was built over the original work by him. So i will release the next version. I am sorry to all you ppl waiting but iphysics final version might take a bit longer than expected, i have a lot of personal issues nowadays and other stuff so nowadays i am getting almost NO time to work on iphysics.

hello, i need a little help..

Your 'wrapper' is great, but there are some features that i have missed from the old wrapper...

I need to position and control all the wheels manually (like in the old wrapper) this means i could have 4x4, 2x4 etc , and all wheel steer machines.. also i need the back wheels different size than the front wheels.. (this was possible in the old newton irrlicht wrapper, but the old wrapper wont work with irr 1.2...)

Could you help me? i looked but i couldent find anything

About the suggested idea for setting position of an entity based on mouse position that was a reply to my earlier question, taken for granted that it would work without errors (even if mouse move very fast - a cap can be put on that), the ->setPosition() can't be used with the mouse co-ords as they are (2d Screen co-ords) so how would you go about setting the object at world co-ords (0,0,0) and the invisible mouse there (in 3d) and then moving the mouse would move the object?

I'm not sure if one of Irrlicht's functions that translates screen to 3d is of use here?

Basically how to get the correct 3D co-ords to feed to entity->setPosition(x,0,z)... with y being fixed at 0 in this case so that the object moves along a plane.

edit > I suppose you could just centre the mouse and add/minus floats to the object x/z co-ords based on the mousex<0 mouseX>0 (and y) method but that wouldn't take into account acceleration. hmmmm

thanks

@Rusty06: Damn, somwhere somehow i removed the car.cpp file from the project! I havent changed anything in car.cpp so you can still add it and compile it yourself, sorry i cant do it for you rit now coz my computers gone totally crazy now adays!

@greylantern: I didnt get your point there, but you could use:

virtual core::line3d< f32 > getRayFromScreenCoordinates (core::position2d< s32 > pos, ICameraSceneNode *camera=0)=0

You just give it the 2d coords and it will give you a 3dline!

so i should include the car.cpp to my composition? or should i include the car.cpp from the old wrapper to the new wrapper and recompile the new wrapper? maby somone can help

its realy a great wrapper but i need this function ALOT

i too have such errors

MSVCRT.lib(MSVCR80.dll) : error LNK2005: _free ist bereits in LIBCMT.lib(free.obj) definiert.
MSVCRT.lib(MSVCR80.dll) : error LNK2005: _malloc ist bereits in LIBCMT.lib(malloc.obj) definiert.

i dont really understand how to solve it can someone also explain me how to solve it?

greets,

@Rusty06: My computer is better now, ill try and implement it myself cause i just noticed that you wont be able to do it, you have to do a lot of internal changing for that! Neways ill post bak here with a link to the car included file!

@Halan: What compiler are you using, what os?? And when does it show this error?

Are you mixing libs that have static CRT and dymanic CRT?

Halan · Post by **Halan** » Tue Jan 30, 2007 4:16 pm

well i linked against newton dynamic dll and irrlichts dynamic dll iphysics is static afaik but i dont really know what CRT is

greets,
Halan

btw: is there no character controller inside? the whole application seems a bit weak i mean i can use ragdolls or easilly use hitboxes etc...
but i like the idea keep on going

sio2 · Post by **sio2** » Tue Jan 30, 2007 4:21 pm

MSVCRT.lib is MicroSoft Visual C RunTime. CRT is the C-Run Time functions. If you link to CRT functions in msvcrt.dll (via msvcrt.lib) in one lib but use static CRT functions in another lib the linker can't work out which it should use - hence the message. This can be a pain to track down - do you have a test project you could upload?

Halan · Post by **Halan** » Tue Jan 30, 2007 5:00 pm

yeah well ill export it to an msvc++ project (atm it is codelbock but im using msvc 2005 as compiler)

uploading

Halan · Post by **Halan** » Tue Jan 30, 2007 5:05 pm

well i mmm i cant convert it seem

but one querstion which newton lib i do have to link i linked the one in the "dll" folder buy maybe im totally wrong
btw theres no project setup tutorial on the iphysics

Character controller is there in the newer version! BTW the app looks weak because of no official release or so i guess, i am planning one soon with ragdolls and joints! They are already implemented but ragdolls is causing a few probs, will release it soon, so keep updated! Thnx!
