Microsoft Windows integration? - constructworker - 12-10-2020
So how would tilengine be setup to render into a native win32 application?
I'm familiar with how to setup a win32 program and make a window/process messages.

Hi,
I don't quite understand what you mean with a "native win32 application". When you compile a program that uses Tilengine with Visual Studio or mingw32, the resulting executable is a native win32 application, you cannot run in under linux or in a raspberry. The generated window is a native win32 window too.

Hi, well in the docs it uses a built-in tilengine function to make a window without invoking win32 api functions, but
afaict the docs say you can use the tilengine with any operating system to render to their native windows.
For instance
Code:
HWND window;
CreateWindowExW();Code:
TLN_createwindow()the docs say you can use tilengine as a slave renderer?
I was under the impression it was used much like Vulkan in that you can use a win32 surface and then make a compatible surface with vulkan to render to.

It uses SDL2 to display graphics.
not sure if it uses hardware acceleration to display them, but it may use Open GL since it's open source and cross-platform, but again, not sure at all.
Update : It uses OpenGL

Hi,
Yes, you can use Tilengine without its built-in window. In this case is up to you, the integrator, to create the render target in your windowing environment. Tilengine expects a 32-bit RGBA surface. This chapter in the documentation gives the details:
http://www.tilengine.org/doc/md_rendering.html
In Windows, you must use DirectDraw, Direct3D, OpenGL or whatever graphics API that allows you to create and use RGBA surfaces. The built-in window uses the cross-platform library SDL2, that in turn selects the best graphics API available on host operating system. Tilengine itself doesn't require any kind of graphic acceleration, you can even draw to a memory buffer.
This example showcases how to draw to a Java applet:

And here is a tutorial on how to integrate inside a Unity project:

Even if you check the source code of Window.c, you can see how the built-in window uses SDL2:

Does the base Tilengine use hardware acceleration?
RE: Microsoft Windows integration? - megamarc - 12-11-2020
No, the base Tilengine doesn't use hardware acceleration at all, it's entirely software based on CPU alone. SDL2 library that underpins the built-in window does use hardware acceleration.

Ah I understand why it takes half of my GPU now. How can I enable it?
RE: Microsoft Windows integration? - megamarc - 12-12-2020
Sorry I don't understand the question. Enable what?
If GPU usage is high, you may have a low-end system. Disable CRT effect (enabled by default) by pressing "backspace" key once

Sorry if my question wasn't clear, I meant, how can I enable hardware acceleration support?
