I'm attempting to change terrain example (#11) to have the 3D view take up less space on the gui, so I can have buttons and the like, but whatever I try changing doesnt do anything, the view still takes up all gui space.

So I have added it to a child window instead, and got it working, except when the gui is deactivated and then activated again, then my keyboard goes ding ding ding when using the wasd keys for movement.

The code.. (TerrainApp.au3 in the D3D example #11)

#include "Camera.au3"
#include "Terrain.au3"
#include <GUIConstantsEx.au3>
#include <Misc.au3>
#include <WindowsConstants.au3>

Hold down right mouse button and use wasd for movement, then try deactivating the gui by doing something else like notepad or focus on this browser window, and then go back to the gui, then it goes ding ding when using the wasd keys.

I've been reading around ofcourse and tried some stuff like the "empty label trick" I've heard mentioned, and guiswitch() and setparent(), but cant get it working,

Ultimately, get rid of the child window and just have the D3D view not take up all the gui space. :graduated:

Thanks.

Your attached code is not executable without the dependencies! This is the reason you got no answer!

Try GUISetAccelerators() for all keys that are used. Use a dummy function for them.


Programming today is a race between software engineers striving to
build bigger and better idiot-proof programs, and the Universe
trying to produce bigger and better idiots.
So far, the Universe is winning.

No, I dont get any answers because ppl are lazy :(

I'll look into that, thanks.

If I'm unsuccessfull I'll look into making another example (new thread!) that doesnt require any extras. :graduated:

There are those that believe that the perfect heist lies in the preparation.
Some say that it’s all in the timing, seizing the right opportunity. Others even say it’s the ability to leave no trace behind, be a ghost.
