2D water simulation using a C++ dll

Recommended Posts

DatMCEyeBall

I wrote this a while ago and only recently implemented shading.

The current shading algorithm could use some improvements.

Most of the source is based from here

The .dll source is also in the archive (made with Visual Studio 2012 Express).

2D Water simulation using a C++ dll.7z

If you use a x64 bit OS then:

For anyone having trouble running this on a x64 OS, set #AutoIt3Wrapper_UseX64=n (OP code assumes you are running x86 AutoIt).

 

EDIT:

Added an example using a .gif file (split into frames).

I can't get it run. msvcp110d.dll was missing but after downloaded it, nothing happens when starting the script.

Tested on Win 8.1 and 3.3.10.2.

Cool, works now. I will check whether it can be loaded from memory and use it for my watermark app.

Btw, I tried several times to learn C++ using MS VS but it is a overkill with plenty of features which I don't need when being a C++ noob besides to use the IDE environment.

A mentor would be nice...

Cool, works now. I will check whether it can be loaded from memory and use it for my watermark app.

Look at the first line of WaterSim.au3 (the Global Enum line).

Check the UseBuffer1 flag in the params structure (forgot the Enum's name) if so use the HM (height map) #1 if not use #2

Add to the data (+=) at the specified location an amount (it's a height map used by the .dll so add a number like 512 or more - depends on what you prefer)

The height map is a 1D array, I think the main .au3 file still has a _PixelIndexFromXY (or similar) function, use it to convert XY co-ordinates into the index of the array. 

Call the NewFrame function to draw and flatten the water.

I can write you something special instead. If you want me to do so then please PM me.

A mentor would be nice...

Mentor?  :sorcerer:

C++ for dummies(link to .pdf) is what I used to learn it, VS is just there for convenience.

I mean rather to load the DLL from the memory.


Thanks for the Dummy stuff but I've already a lot of C++ documentations (incl. this).  :whistle:

For anyone having trouble running this on a x64 OS, set #AutoIt3Wrapper_UseX64=n (OP code assumes you are running x86 AutoIt).

I'm adding this to the OP.

What exactly is bothering you with MS VS C++?

If you have a problem then Google it - that's what I do.

I find it hard to use the editor - it is so oversized compared to SciTE. Anyhow, if I find enough motivation I will try again.

      I'm building a tool to remotely monitor CPU usage on my server.
      I have a working tool but I have a few issues I'd like some help with.
      1. The app uses more system memory on a continual growth rate...  It eventually starts displaying strange artifacts and the background flashes between black and and white behind the GDI+ elements.  I determined this couldn't be left to run for any amount of time (greater than 15-20 minutes) - Very frustrating.
      I suspect it's because it keeps drawing new GDI+ elements to replace the previous cycle ... the $bar1 = "" is enough to remove the image and allow the new image to be drawn there, but I don't have a handle for the original GDI+ element to throw it away... Not sure where they go...
      I also suspect there could be a better way to do what I'm doing here, but from a problem solving perspective - this is what I came up with - I will accept suggestions for how better to accomplish the same / better or acceptable results  
      I will not however accept corrections on grammar, punctuation or commenting - I didn't comment this as I was going, I use the variables that make sense to me (or as they were when I lifted them from the scraps I found on the internet) and you can never be too careful with punctuation.
      2. I have a WMI query that is used to remotely pull the CPU data from the server - if I supply the wrong credentials the app crashes... I tried to make it show an error and go back to allow me to try again ... doesn't work. Any help with catching that error and preventing the crash would be super helpful. (works great if the credentials are correct; domain or local)

      Hello,
      I am making a program where the button is an image that "changes" when specific conditions are fullfilled. Problem is that these images have different dimensions and when a smaller picture is displayed over a bigger one both will be seen, therefore i would like the images to be hidden, invincible or, alternatively, deleted.
      I have tried using _GDIPlus_GraphicsClear() with no luck
      However that might just be me not using it right as im quite new to autoit
      Here is the code if you want to test run it:
      Thanks to everyone helping!

One workaround is to use full screen capturing (F11/F12) or "Grab Screen" function! Or try double click with rmb on listview items (beta).

      Autoit version: 3.3.14.5
      System: Windows 10 Home x64
      C++ IDE: Code::Blocks 17.12
      When I call the Dll that I wrote it give me how return value -1073741819 and exit value 3221225477, I tried changing variables type but it didn't work.
      This is the Autoit code:
      #Region ;**** Directives created by AutoIt3Wrapper_GUI **** #AutoIt3Wrapper_UseX64=n #EndRegion ;**** Directives created by AutoIt3Wrapper_GUI **** $dll = DllOpen(@ScriptDir & "\Test.dll") DllCall($dll, "NONE", "TestFunction", "STR", "1 string", "STR", "2 string", "STR", "3 string", "INT", 1) ;Here crash and doesn't show the MsgBox MsgBox(0, "", @error) DllClose($dll) This is the main.cpp code:
      #include <iostream> #include <Windows.h> #include "main.h" using namespace std; extern "C" { DECLDIR void TestFunction(std::string string1, std::string string2, std::string string3, int number1) { std::cout << string1 << std::endl; std::cout << string2 << std::endl; std::cout << string3 << std::endl; std::cout << number1 << std::endl; } } And that is the main.h:
      #ifndef _DLLTEST_H_ #define _DLLTEST_H_ #define DLL_EXPORT #if defined DLL_EXPORT #define DECLDIR __declspec(dllexport) #else #define DECLDIR __declspec(dllimport) #endif extern "C" { DECLDIR void TestFunction(std::string string1, std::string string2, std::string string3, int number1); } #endif  
      And the values of the variables that write to the SciTe console ae completely different.
      Here I attach the console output of the SciTe editor:
      >"C:\Program Files (x86)\AutoIt3\SciTE\..\AutoIt3.exe" "C:\Program Files (x86)\AutoIt3\SciTE\AutoIt3Wrapper\AutoIt3Wrapper.au3" /run /prod /ErrorStdOut /in "C:\Users\DragonFighter\Desktop\Dll test.au3" /UserParams +>10:30:08 Starting AutoIt3Wrapper v.17.224.935.0 SciTE v.3.7.3.0 Keyboard:00000410 OS:WIN_10/ CPU:X64 OS:X64 Environment(Language:0410) CodePage:0 utf8.auto.check:4 +> SciTEDir => C:\Program Files (x86)\AutoIt3\SciTE UserDir => C:\Users\DragonFighter\AppData\Local\AutoIt v3\SciTE\AutoIt3Wrapper SCITE_USERHOME => C:\Users\DragonFighter\AppData\Local\AutoIt v3\SciTE >Running AU3Check (3.3.14.5) from:C:\Program Files (x86)\AutoIt3 input:C:\Users\DragonFighter\Desktop\Dll test.au3 +>10:30:08 AU3Check ended.rc:0 >Running:(3.3.14.5):C:\Program Files (x86)\AutoIt3\autoit3.exe "C:\Users\DragonFighter\Desktop\Dll test.au3" --> Press Ctrl+Alt+Break to Restart or Ctrl+Break to Stop �Á+���Uø‰q�‰A�‹O`ÆEÿ�èèÖÿÿƒÄ €}ÿ!>10:30:10 AutoIt3.exe ended.rc:-1073741819 +>10:30:10 AutoIt3Wrapper Finished. >Exit code: 3221225477 Time: 3.414

      Ciao
      I would like to control an ATEM Video Mixer from autoit. I downloaded his SDK which is written in c ++ and I found the sequences to interface, but I was not able to convert the script to self.
      The instructions say to follow this sequence:
      and to connectTo with C++ is:
      string address = "192.168.1.240"; _BMDSwitcherConnectToFailure failureReason = 0; IBMDSwitcher switcher = null; var discovery = new CBMDSwitcherDiscovery(); discovery.ConnectTo(address, out switcher, out failureReason); From Blackmagic SDK:
      IBMDSwitcherDiscovery::ConnectTo method
      The ConnectTo method connects to the specified switcher and returns an IBMDSwitcher object interface for the switcher.
      Syntax HRESULT ConnectTo (string deviceAddress, IBMDSwitcher** switcherDevice, BMDSwitcherConnectToFailure* failReason); Parameters: deviceAddress in Network hostname or IP address of switcher to connect to. switcherDevice out IBMDSwitcher object interface for the connected switcher. failReason out Reason for connection failure as a BMDSwitcherConnectToFailure value. So, I have I tried these solutions but with non success:
      $DllName =@ScriptDir&"\BMDSwitcherAPI.dll" $result = DllCall($DllName, "none", "IBMDSwitcherDiscovery::ConnectTo" & @CRLF) ConsoleWrite("DLLCall Result: " & $result & @CRLF) and I have tried also create an Object (That I think is the best way solution):
      #include <MsgBoxConstants.au3> $oSwitcher=ObjCreate("IBMDSwitcher") If IsObj($oSwitcher) Then MsgBox(64, "", "Object $oSwitcher created successfully") EndIf $oAtem=ObjCreate("IBMDSwitcherDiscovery") If IsObj($oAtem) Then MsgBox(64, "", "Object $oAtem created successfully") EndIf $failureReason =ObjCreate("_BMDSwitcherConnectToFailure") If IsObj($failureReason) Then MsgBox(64, "", "Object $failureReason created successfully") EndIf $oMyError = ObjEvent("AutoIt.Error", "MyErrFunc") ; Install a custom error handler Global $errore,$oSwitcher1 $oAtem.ConnectTo("192.168.1.36",$oSwitcher,$failureReason); ; This is the custom error handler Func MyErrFunc() $HexNumber = Hex($oMyError.number, 8) MsgBox(0, "", "We intercepted a COM Error !" & @CRLF & _ "Number is: " & $HexNumber & @CRLF & _ "Windescription is: " & $oMyError.windescription & @CRLF & _ "Source is: " & $oMyError.source & @CRLF & _ "Description is: " & $oMyError.description & @CRLF & _ "Helpfile is: " & $oMyError.helpfile & @CRLF & _ "Helpcontext is: " & $oMyError.helpcontext & @CRLF & _ "Lastdllerror is: " & $oMyError.lastdllerror & @CRLF & _ "Scriptline is: " & $oMyError.scriptline) EndFunc ;==>MyErrFunc But the result is:
      We intercepted a COM Error !
      Number is: 000000A9
      Windescription is: Variable must be of type 'Object'.
      Source is: 
      Description is: 
      Helpfile is: 
      Helpcontext is: 
      Lastdllerror is: 0
      Scriptline is: 17
      The BMDSwitcherAPI.dll is registered in system. Can someone help me?
      Grazie
      Marco
