hi, this is my first big project with GDI+,

it tries to simulate gravity motion (this is the most difficult), but also uniformly accelerated motion and constant motion,

it also shows additional informations, and allow the user to pause, change simulation speed, and more features i'm constantly improving and adding.

well, here's the code

#include <GDIPlus.au3>
HotKeySet("{ESC}", "ExitProgram")
HotKeySet("{SPACE}", "TogglePause")
HotKeySet("{+}", "RaiseSpeed")
HotKeySet("{-}", "LowerSpeed")

Opt("GUIOnEventMode", -1)
Global $PenAxes, $Pen, $Brush, $Graphics, $BitMap, $Buffer, $CapAxes, $CapNorm

it was italian, i turned most of it in english, but sorry anyway for bad english.

Here's the questions:

-Why FPS are so low? I'm comparing with games that easily hit 60FPS or more. is it me or AutoIt limits?

-It notably go faster when "additional info" are disabled ("Show" menu). i guess it is because of less calculations to do... i tryed to change Sleep() duration in relation to FPS to compensate but i didn't succeed. anyway to fix this?

-this is a windowed release. i started with a fullscreen one that had show/hide (like axes, informations, vectors) functions activated with Checkboxes and Radio buttons, that worked fine. Now functions are activated by clicking on the menu, but there is a heavy delay between click and actual activation. anyway to fix that?

also, general opinions are welcome.

thanks!

edit: updated the script - added disabled hotkeys when window is not active, changed the 0x speed, added the $HWidth and $HHeight variables to reduce calculations

edit2: solved most problems - added resize support, improved general performances.

If you reduce speed such that the $simulationspeed reaches 0 then it seems to lock up with no way of resuming. Maybe this to fix...

nm (plus sign involves a shift key).

setting a speed other than 0x and hitting space resumed normal function.

Func LowerSpeed()
    If $SimulationSpeed > 1 Then $SimulationSpeed = $SimulationSpeed -1
EndFunc

The main problem is the calculation! You need to try to optimize the math, e.g. not calculate constants every time.

I'm not so good in optimization (Spiff59 is much better :() but here my try:

Thanks, it goes much faster!

i've didn't knew about the AdlibRegister() function, but there is a problem with that, it does not change things to visualize.

i mean, if i use AdlibRegister, and then toggle show axes, or vectors, or change motion type, it does not change. Maybe the AdlibRegister makes the Draw function not to accept external variables?

another question: if i round numbers every time, does it go faster because of less calculations, or slower because rounding is another calculation?

I would say "much faster" is a little bit exaggerated :graduated:

With AdlibRegister("Draw", 40) it is working for me.

You can use GUICtrlSetOnEvent() function to control the menu items, too.

thanks, i solved most of the problems.

the Adlibregister() stuff works now. it didn't because there was a sleep(10) inside the function called every 15 ms.

i switched every control in GUICtrlSetOnEvent(), and runs better now.

i also added the possibility to resize and maximize.

i will keep improving the script, thanks again for your help and remember that general feedbacks are always welcome!

(note: i updated the script in the first post)

Add to line 103 (just after $Buffer = _GDIPlus_ImageGetGraphicsContext($BitMap)) the line _GDIPlus_GraphicsSetSmoothingMode($Buffer, 2) to get a smoother display.
