Mouse click on dirextx objects [help needed]

I've Searched every part of the forum and almost all the internet googling the answer.
2 Week's have passed, still looking for an answer, the thing is:

I wanna to make a simulation of mouse click in a certain point of screen.
This point is inside a game called Point Blank, by On Game. Im trying to do the following automatically.

Open up the game. Fill in the account. Put the password. Click the login button. Double Click the server and Double Click the room.

The Problem:
The is no way on posting,sending messages or other windows api that would do such a thing. (at least that i've found!)

I've tryed:
PostMessage
SendMessage
SendInput

Ideas:
Is there a way to do it in a lower level programming language? If yes, please how?

Any doubts post a reply.

Thanks in Advance

There is a mouse_event sub which should be used

Code:

---

Public Class Form1

    Private Declare Function SetCursorPos Lib "User32.dll" (ByVal X As Int32, ByVal Y As Int32) As Int32
    Private Declare Sub mouse_event Lib "user32" Alias "mouse_event" (ByVal dwFlags As Int32, ByVal dx As Int32, ByVal dy As Int32, ByVal cButtons As Int32, ByVal dwExtraInfo As Int32)
    Private Const MOUSEEVENTF_LEFTDOWN As Int32 = &H2
    Private Const MOUSEEVENTF_LEFTUP As Int32 = &H4
    Private Const MOUSEEVENTF_RIGHTDOWN As Int32 = &H8
    Private Const MOUSEEVENTF_RIGHTUP As Int32 = &H10
    Private Const MOUSEEVENTF_MIDDLEDOWN As Int32 = &H20
    Private Const MOUSEEVENTF_MIDDLEUP As Int32 = &H40


    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        ' Go to point 800, 300
        SetCursorPos(800, 300)
        ' Simulate left click.
        mouse_event(MOUSEEVENTF_LEFTDOWN, 0, 0, 0, 0)
        mouse_event(MOUSEEVENTF_LEFTUP, 0, 0, 0, 0)
    End Sub

    Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
        ' Go to point 40, 460
        SetCursorPos(40, 460)
        ' Simulate right click.
        mouse_event(MOUSEEVENTF_RIGHTDOWN, 0, 0, 0, 0)
        mouse_event(MOUSEEVENTF_RIGHTUP, 0, 0, 0, 0)

    End Sub

End Class

hey dude!

Thanks for replying, but this functions is only aplied to desktop apps. So it wont work.

Thanks anyhow.

Any other idea?

See ya.

All you are doing is making a macro. 4x2y's code should work just fine. It simulated mouse clicks which should work on any game.

As you said, it "SHOULD", but it doesnt.

Thanks anyway.

Anyother tip or help?

Yes, it should. If it doesn't then you are doing something wrong.

Can you describe your setup better? Is the game not a desktop app? Is your app not a desktop app?

I've used the method above on DirectX games plenty of times.

Ok, It WORKS ON ALMOST ANY DX GAME like Warcraft and so on...

This game made by OnGame it doesnt. My app is a normal Vb.Net one.

Nothing unusual.

Take a look at "Point Blank" if you can and see by yourself this strange thing.

I am so glad that there are a lot of people trying to help, Thanks You. :)

Any other Idea would be greate!

See ya.

The code

Code:

---

        mouse_event(MOUSEEVENTF_LEFTDOWN, 0, 0, 0, 0)
        mouse_event(MOUSEEVENTF_LEFTUP, 0, 0, 0, 0)

---

Simulates left click regardless of what is on the screen.

I don't have "Point Blank" game to test the code with it, i have two question, is the game configured to use mouse? are you sure you are click on the correct point?

Yes, it uses the mouse and yes too I am sure that i'm clicking on the right place.

I tryed the same code and could not get it working...

Ok, i think that is impossible to do so.

Consider this Thread finished and unsolved.

3 Week's of sarching and no answer. But ok.

Thanks for all the help requested.

See ya.

You got the answer. I just don't think you are doing it correctly.

If you can click it with a real mouse, you can use the code suggested by 4x2y to click it. It is basically the same thing.

@henriqueshb

I have got an idea it maybe the reason for the problem, just give it a try!!!

How do you execute the code?

I mean, if you click on a button in your main form, probably the cursor go to the game and the click by mouse_event is just transfer the focus from your form to the game window, so try to send left click twice

Code:

---

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        ' Go to point 800, 300
        SetCursorPos(800, 300)
        ' Simulate left click.
        mouse_event(MOUSEEVENTF_LEFTDOWN, 0, 0, 0, 0)
        mouse_event(MOUSEEVENTF_LEFTUP, 0, 0, 0, 0)

        mouse_event(MOUSEEVENTF_LEFTDOWN, 0, 0, 0, 0)
        mouse_event(MOUSEEVENTF_LEFTUP, 0, 0, 0, 0)
    End Sub

---

or put the code in a timer event to be sure it will be executed when the game window has the focus.

Code:

---

    Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
        ' Go to point 800, 300
        SetCursorPos(800, 300)
        ' Simulate left click.
        mouse_event(MOUSEEVENTF_LEFTDOWN, 0, 0, 0, 0)
        mouse_event(MOUSEEVENTF_LEFTUP, 0, 0, 0, 0)
    End Sub

        mouse_event(MOUSEEVENTF_LEFTUP, 0, 0, 0, 0)
    End Sub

Yes man, Actually i did the last part of the code.

Puted into a timer and dit not get it working.

No more ideas.

I dont know, only in this game it doesnt work.

Any other idea?

Thanks at all.

The nearest i reached was when not focused on the game window and then sent a click it got focused on the game window,
so it is clicking, but the game does not consider the things that comes from the normal way we post the messages of this kind,
like clicking, i don't realy know why. But it does not respond to those commands we have been talking...

Anyway, thanks for the help till now. And also sorry for the english mistakes...

No more help?!

Ok then, thanks at all anyway. Seeya.

According to MSDN, the mouse_event has been superseded, so let's try SendInput

I have created VB6 code for using SendInput, but i have trouble converting it to VB.NET (specially trouble with CopyMemory API function), so try it with that game and if it worked then convert it to VB.NET and please share the result. :D

Code:

---

Option Explicit
Private Const MOUSEEVENTF_LEFTDOWN As Long = &H2
Private Const MOUSEEVENTF_LEFTUP As Long = &H4
Private Const INPUT_MOUSE As Long = 0

Private Type MOUSEINPUT
    dx As Long
    dy As Long
    mouseData As Long
    dwFlags As Long
    time As Long
    dwExtraInfo As Long
End Type

Private Type GENERALINPUT
    dwType As Long
    xi(0 To 23) As Byte
End Type

Private Declare Function SetCursorPos Lib "user32" (ByVal X As Long, ByVal Y As Long) As Long
Private Declare Function SendInput Lib "user32.dll" (ByVal nInputs As Long, pInputs As GENERALINPUT, ByVal cbSize As Long) As Long
Private Declare Sub CopyMemory Lib "kernel32" Alias "RtlMoveMemory" (pDst As Any, pSrc As Any, ByVal ByteLen As Long)


Private Sub Command1_Click()
    Dim typInputType As GENERALINPUT
    Dim typMouseInput As MOUSEINPUT
   
    SetCursorPos 900, 40
   
    typInputType.dwType = INPUT_MOUSE
   
    ' Send left button DOWN
    typMouseInput.dwFlags = MOUSEEVENTF_LEFTDOWN
    CopyMemory typInputType.xi(0), typMouseInput, Len(typMouseInput)
    SendInput 1, typInputType, Len(typInputType)
   
    ' Send left button UP
    typMouseInput.dwFlags = MOUSEEVENTF_LEFTUP
    CopyMemory typInputType.xi(0), typMouseInput, Len(typMouseInput)
    SendInput 1, typInputType, Len(typInputType)
End Sub

---

Ok, I'll try it later, but it will be in something like 12 hours...

I'm at work and got go to the university later...

So, see you later, I'll convert and share later for sure.

This is not that hard wait till that or take a look here tomorrow.

Just for you to know, i have already tryed the sendinput function but does not work either.

Strange, I tested SendInput and it works with that game, see attached video, when i click on Command1, the cursor go to the game's close button and simulate left click and as you can see the confirmation message appear.

mouse_event was not work as you said!!!

BTW: i cannot start the game, as when i click on its start button, the game takes sometime to load then terminate.

Actually, this is not the game part, in this part everthing works....

The part of the game that does not work is after the loading part...

And a NOTICE:
I found what we should take a look.

And it is "dinput8.dll" this is what does the magic.

If this dll is not working you cant send any input to the game even using the real mouse or keyboard.

In this way I think that should have some kind of communication with this dll, I googled it but could not found any.

And 4x2y your probably the best guy i have ever know, thanks for all you help.

See ya.
