Hi Michael
i was writing my post above at the same time you was writing your post 12:08 pm _12:14 pm, so i have not seen it until today. great work and many new functions to test. i suggest a new installation file will be easier for the new users.
regards

@MPZ: OMG! I about **** myself when I saw this update! THANK YOU SO MUCH FOR ADDING THREAD SAFE & UNICODE EXECUTABLES! =DDDD

Cannot WAIT to see what's in store for V.0.34! :D

thank Michael for the Gear introduction, the example posted here http://www.purebasic.fr/english/viewtop ... 50#p424445 as a future plan now implemented
i have tested it, and want the gear to rotate under impulses such as MP_EntityAddImpulse(Mesh, 0, -0.03, 0 , -2.0,0, 0)
i propose the coordinates here as in this picture:
Image
so the left gear are rotated and affect the right gear.

the 3 cubes are just a position sign
note that in MP_EntityPhysicBody(Mesh , 5, 10) there is number 5 which is a new type other than before, i hope it will work also with a dynamic holes such as a torus with a hole falling down over a stick, i will try that.
a logical wish is if there is a motor function will be great, i saw MP_EntitySetVelocity() but either i don't know how to use it or it does not work yet. the motor function like the EnableHingeJointAngularMotor used in the new example CarPhysic.pb in C:\PureBasic\Examples\3D\Demos
here is Michael demo run by "MP_EntityAddImpulse" to show the case. i have tried also a 2 gears like i have posted here http://www.purebasic.fr/english/viewtop ... 50#p421363
and runs but stuck too much, may be we need to reduce the triangles, so if successful i will post it.
PS: just now i saw Alexi asked about clothes here http://www.purebasic.fr/english/viewtop ... 36&t=57073 i saw somewhere a clothes demo and even a clothes which can be torn, are there clothes in DX ??

another play with gear demo, added an axes, and a teapot
increase the force (-0.01 ) if you want in line 81

Hello ApplePi,

you understand mp3d perfectly. Thanks for your good demos...

i think the best counterpart of "EnableHingeJointAngularMotor" is the command MP_EntitySetOmega(Entity, xOmega.f , yOmega.f ,zOmega.f)

You can exchange the

Code: Select all

MP_EntityAddImpulse(Mesh, 0, 0, -0.01 , -1.5,0, 0)
with

Code: Select all

        If MP_KeyDown(#PB_Key_Up)
          omega.f + 0.5
        ElseIf MP_KeyDown(#PB_Key_Down)
          omega.f - 0.5
        EndIf  
        MP_EntitySetOmega(Mesh, 0 , omega ,0)
With cursor up and down you can speed up the gears

You find a description of omega in the
http://www.newtondynamics.com/wiki/inde ... ySetOmega

P.S. All newtondynamics 3.1 functions are includet, but i have not all as mp3d commands implemented. If you need or want some of the newtondynamics commands, tell it and i will make it...

IMHO there is no need you to ask about to implement or not some features which are very interesting, I mean, ¿why do not you implement interesting features to perform a better and better product without asking users?

By the way; can you make the function MP_ScrollSurface() faster? It seems too slow!
This tip shows it ("galaxy.png" is a 1680x1050 pixels image) in a modern pc with modern VGA:

Code: Select all

ExamineDesktops()
Global bitplanes.b=DesktopDepth(0),RX.w=DesktopWidth(0),RY.w=DesktopHeight(0),s_bg.i
MP_Graphics3D(RX,RY,0,0):MP_VSync(1)
SetWindowTitle(0,"SpaceKnight")

Cam=MP_CreateCamera()
Light=MP_CreateLight(1)

Surface=MP_LoadSurface("galaxy.png")

MP_CameraLookAt(Cam,MP_EntityGetX(polygon),MP_EntityGetY(polygon),MP_EntityGetZ(polygon))

MP_SurfaceSetPosition(Surface,0,0,1)
MP_SurfaceSrcRect(Surface,0,0,1680,1050)
MP_SurfaceDestRect(Surface,0,0,RX,RY)

While MP_KeyUp(#PB_Key_Escape) And WindowEvent()<>#PB_Event_CloseWindow
  MP_ScrollSurface(Surface,0,1)
  MP_DrawText(10,10,"FPS = "+Str(MP_FPS()) + "; SurfaceHeigh = "+Str(MP_SurfaceGetHeight(Surface))+"; SurfaceWidth = "+Str(MP_SurfaceGetWidth(Surface)))
  MP_RenderWorld()
  MP_Flip():Delay(16)

many thanks michael, yes the MP_EntitySetOmega function behaves like the motor function and it provides a stable speed for the gear. and even it works better for the many polygons gear i have posted before but i'm now searching for a more suitable gear model with low polygons count. certainly there will be more mechanical toys we can make from those new functions.

Hi,

@Psychophanta i think you had made a mistake in your demofile.

If you use "MP_VSync(0)" and dont use "Delay(16)" i have over 1000fps and the picture is scrolling 1000 pixel in one second. i think not the procedure is slow, it is the delay...

@applePi,

i hope you find some better models and we can make a mechanical clock with physic function or a game to combinate entitys with physic functions...

Hello, @MPZ. Is there a small sample demo which allows for 2D map scrolling & 2D frame animation from a sprite sheet?

The Delay(16) just forces the loop program to perform all the task in 0.3333 milliseconds or less.
My demofile demonstrates that the loop takes more than 0.3333 milliseconds per loop, and this is a lot of time.
A deeper view demonstrates that is just the MP_ScrollSurface() command which consumes too much time.

Thanks!

Hi


@Mythros

in the MPDemos you find the "TileEngine" folder. There is a tile editor and and easy "Dungeon Crawler" program with "2D map scrolling & 2D frame animation" i hope this helps...

@Psychophanta,

to copy a 2 Gbyte grafik file into the backbuffer of dx 9 you need time. i have no idea how to speed it up. But how man fps do you have exactly without delay? I have 1100, that means you must calculate 1 second / 1100 fps = 90 micro second and not 333 micro second for one pixel scrolling. The delay command is very inaccurate and you cant use it for calculation.

Have you onother programm to compare? Have you test the purebasic image funtions or a other dx9 funtions? Perhaps you have another demo program then i can check it out an make the procedure faster....

Without debuger and just with copy&paste your 'galaxy.png' tip i get: FPS = 146

With the other example i get: FPS = 252

Why do you get more FPS in the 'galaxy.png' example than in the other? :shock: :?:
Can you test it in other machine of year 2006 to 2009 ?
