 | The first Collisionsabfrage with the Viereck 128X128 Pixel.
I form the Viereck now Black ex, so möglichs many colours taken go can.
there otherwise others colours in the Viereck also The Collisionsfarbe having ,addressed go.
If the car the "Viereck" touched ,which herewith prepares watts : ogl("glReadPixels",140,140,128,128,~GL_BGRA,~GL_UNSIGNED_BYTE,ogl_rgb#) , becomes the worth 255 spend.
Massgebend are The colours RGB greater 252. Can anytime in the CPP-File Change.
have first once The request with the DEV C++ made or DLL prepares., because I in ASM first again failed be.
The DEV C++ Source-Files are too with thereby.
The zipper is appended.

| here sees one too The enormous speed from the DEV C++ Dll.
If itself the car ausserhalb the Rechteckes moving, must 128X128x3 inquire erfolgen whether something happens and it moving itself still super quick without To to judder.
the was first my erstes target. an fliessende movement with plenty controls.
a irregular body could one too inquire.
on it becomes now getüftelt.
try too this still in ASM umzusetzen.

| here's the ASM-code.
before, before the xpse used becomes , must these Änderung erfolgen:
ogl("glReadPixels",140,140,128,128,~GL_BGRA,~GL_UNSIGNED_BYTE,ogl_rgb#) > GL_BGRA Remove
ogl("glReadPixels",140,140,128,128,32993,~GL_UNSIGNED_BYTE,ogl_rgb#) > The number 32993 reinsetzen
The reason is, the in the INC-File these Variable not yet reingesetzt watts.
whom appeal with the variables z% and the Drawbefehl too The Variable z% transfer : DrawText 20,160,(stature$("######0 ",z%))
then z%=Call(xpia_getprocaddressm(xpia_hmodule&,"rgb_farbe"),ogl_rgb#,groesse%)

| Ablaufzeiten (gross)the Collisionsabfrage the Rechteckes 128X128X4 with 10000 Schleifendurchgänge :
computer with 1,6 Gigahz
The Profan While-Leerschleife need ca 200ms.
ASM with XPIA/XPSE (DLL) are it 4550 ms .
DEV C++ are it 6210 ms ( a For-Loop).
DEV C++ are it 6260 ms (While-Loop).
with 10000 durchgängen rewards it itself this in ASM umzusetzen, are ca 1,5 sec Difference.

Abbing | your Assembler-routine isn't optimiert. If you tappt im dunkeln umstellst of variables on tab is yet some More drin. ca. 20 percent, wealth I.
These routine keeps your Programmstruktur with, ought to but already work faster:

If 0
AsmStart rgb_farbe (ogl_rgbxy#,groesse%)
mov edi,para2
xor ecx,ecx
mov ebx,para1

mov dl,[ebx+2]
.if al>252
mov eax,255
.break
.endif
.if cl>252
mov eax,255
.break
.endif
.if dl>252
mov eax,255

The Profan While-Loop need ca 200ms.
are You sure, that Profan More as 20-time faster is as ASM? |

| should Empty-Loop heissen, because I integrally supra too of gross promise.
The Test runs with all in the same While-Loop of Profan
I have too time this Freebasic tested to that DLL create.
who in Freebasic a DLL create would like and no ASM can/would like and no "C", is so well bedient.
The Freebasic-DLL need 7400ms means only 1 second longer as DEV C++.
might for Basicprogrammierer , a DLL create would of/ one the best Freewarealternativen his.
with of my Collisionstest-Auswertung with the Freebasic-DLL on-screen on the graphic, is me the Difference optisch not noticed. the Objekt flitzte furthermore still hither and thither withal the Überprüfung/Auswertung.

On each drop must The address always circa "4" go on.

Frank, your need 3,5 sec longer.
incorrect! tab works always faster as Varablen in memory, even if tappt im dunkeln pub are. such Tests have I already dozens implemented.
And so a Assemblerroutine needed never 3,5 sec longer, tappt im dunkeln needed at all only few Millisekunden altogether. even if You with grossen Bitmaps work. You can the gladly with the ProSpeed.dll testing, The numerous Bitmapeffekte knows. Irgendwas goes with your Tests vast schief.
What exactly should The routine because make? tappt im dunkeln fractures still immediate ex, as they a very hellen Farbwert finds. If you a Robotersoftware write want, The The data of/ one Cam auswertet, must You already The amount heller Bildpunkte count. before but the Cambild gray make, or. Black-knows. |
