- Use a SVG asset to allow for better scalability
- Make the controller visible when touching the screen
- Allow for oblique moving by placing finger between two directions
- Add more buttons on the center area of the screen (GUIDE, START, LEFT
STICK, RIGHT STICK) and simplify right area (only four buttons)
- Don't track all fingers, only the ones needed
- Cleanup now unused code
This unifies the ImGui processing for both 2D and 3D engine.
This also make sure we don't destroy ImGui if init failed (like on older
OpenGL).
The destroy callback is also called whenever we destroy the context.
When a 3D game does not support arbitrary resolutions a framebuffer
has to be created. The initSize method can be called multiple times
with different resolutions. Make sure to delete any existing
framebuffer before creating a new.
In the Android port it's possible to configure differnet touch modes
in ScummVM menus, 2D games and 3D games. Add the same possibility in
the iOS port. In Android it's possible to configure a touch based
game controller as well. That's not in scope for iOS in this commit
but can be added in the future.
Add a graphic manager rendering 3D graphics for engines supporting
3D games. The manager is implemented using the 3D graphic managers
for Android and SDL as models.
Most probably Android and iOS can share much more of the code, but
that will be a separate work to refactor.
The iOSGraphics3dManager handles resize since the screen dimension
changes on rotation.
Games not supporting arbitary resolutions, e.g. Grim, are rendered
on an intermediate framebuffer with the size requested by the
engine and then rendered to the backbuffer (a framebuffer bound to
the renderbuffer) and stretched to the screen resolution off the
device.
This commit just adds the manager. It will be utilised in next
commit.
Update gitlab ci worker and update documentation.
- Don't create texture in constructor: it's called before the context is
created
- Don't leak texture names when calling reinit()
- Fix allocBuffer return condition
- Don't call GL if there is no texture object
- Make sure all textures are released and inited
