public class CameraSetup : MonoBehaviour
{
[DllImport("user32.dll")]
private static extern IntPtr GetActiveWindow();
[DllImport("user32.dll")]
private static extern int SetWindowLong(IntPtr hWnd, int nIndex, uint dwNewLong);

void Start()
{
#if !UNITY_EDITOR_
IntPtr hWnd = GetActiveWindow();
MARGINS margins = new MARGINS { cxLeftWidth = -1 };
DwmExtendFrameIntiClientArea(hWnd, ref margins);
SetWindowLong(hWnd, GWL_EXSTYLE, WS_EX_LAYERED);
SetLayeredWindowAttributes(hWnd, 0, 0, LWA_COLORKEY);
SetWindowPos(hWnd, HWND_TOPMOST, 0, 0, 0, 0, 0);
#endif
}
}


this script is supposed to make the current scene background transparent (only if the script is on a gameobject on the scene) and let's the player and other gameobject on the desktop
but the problem is when
1-i load that scene while being in an another one, the background isn't tranparent and all the screen frames are staked
2-if i load the scene but that's the only one from the build, it freeze/crash the game


please i need your help so i can finish what i started

 

How to report your problem productively in the Unity3D forums:

http://plbm.com/?p=220

This is the bare minimum of information to report:

- what you want
- what you tried
- what you expected to happen
- what actually happened, log output, variable values, and especially any errors you see
- links to documentation you used to cross-check your work (CRITICAL!!!)


It appears almost everything about this script is tailored directly to the Win32 User32.dll and its internal endpoints. Don't forget to check that documentation as well. Win32 User32.dll has NOTHING to do with Unity.


The purpose of YOU providing links is to make our job easier, while simultaneously showing us that you actually put effort into the process. If you haven't put effort into finding the documentation, why should we bother putting effort into replying?



If you post a code snippet, ALWAYS USE CODE TAGS:

How to use code tags: https://forum.unity.com/threads/using-code-tags-properly.143875/

- Do not TALK about code without posting it.
- Do NOT post unformatted code.
- Do NOT retype code. Use copy/paste properly using code tags.
- Do NOT post screenshots of code.
- Do NOT post photographs of code.
- ONLY post the relevant code, and then refer to it in your discussion.

 

user32 is because it have something with windows api so i took it

i mean code monkey did the same

 

Might be a better question for code monkey then. I don't see a Unity question here.

If you do see a Unity question, use the steps above to describe it.

 

nevermind i will just wait answers from other peoples
