3DS touchscreen controls toggle #2617

merged 6 commits into from

Hello! This PR intends to replace the current keyboard on the 3DS touch screen with one that can be toggled. This is accomplished by adding an additional row of buttons and shifting the current interface down a bit. I have this marked WIP because while it is compiling fine I think I am missing a step to get .3dsx files working with the homebrew launcher because it crashes to a black screen on startup. This is my first PR here so any guidance is appreciated! 馃槃


Creates an additional row of buttons and moves the current interface down.

Good work so far.

What I dislike here is the big top row for just disabling the screen. IMO this should be made smaller, so the others buttons only loose a bit of height, I would suggest around 20-26 pixels.
This complicates the button logic a bit, though.
I have an old branch for this, but unfinished... The top row has additional space for example for a battery indicator and a restart(F11) button.

Code for the battery indicator (drawing in whole, fixed image should be better):

// in anonymous namespace
u8 battery_charging = 0;
u8 battery_level = 0;
u32 c2d_black = C2D_Color32f(0, 0, 0, 1);
u32 c2d_gray = C2D_Color32f(0.8f, 0.8f, 0.8f, 1);
u32 c2d_white = C2D_Color32f(1, 1, 1, 1);
u32 c2d_red = C2D_Color32f(1, 0, 0, 1);
u32 c2d_orange = C2D_Color32f(0, 1, 1, 1);
u32 c2d_green = C2D_Color32f(0, 1, 0, 1);

// in constructor

// in destructor

// in processEvents()

// in UpdateDisplay() when drawing on bottom screen
// battery indicator
int battery_x = 296;
int battery_y = 6;
u32 color = c2d_gray;
if (battery_charging) {
    color = c2d_white;
C2D_DrawRectSolid(battery_x, battery_y, 0.5f, 18, 8, color);
C2D_DrawRectSolid(battery_x + 18, battery_y + 3, 0.5f, 2, 2, color);
if (battery_level > 4) color = c2d_green;
else if (battery_level > 2) color = c2d_orange;
else color = c2d_red;
for (int i = 0; i < battery_level; i++)
    C2D_DrawRectSolid(battery_x + 2 + i*2 + i, battery_y + 2, 0.5f, 2, 4, color);

There were already plans a couple years back...

So, I made some changes, switched the burger menu icon to an off button, changed the font and darkened it a bit.

If there are plans to introduce other buttons/indicators, it shouldn't be a problem to find a visual solution by making the main buttons smaller and have those extra features on top of the screen, or something like that.

(Note: Will have to convert my version to Inkscape sometime.)

Reset is already mapped to KEY_SELECT.

I like the proposed solution of Schoko for now (the basic version in the middle). I'm a bit worried of users touching this by accident but we have maybe 10 3DS-users, so this shouldn't hurt too many 馃槄

When the battery indicator is ever added this can be still redesigned again (make everything smaller) in a new PR.

I've adjusted the layout and code to work with the proposed basic version in the middle

I do not really understand why you created a new image instead of just taking the one from Schoko but okay...

Imo this is now good enough for inclusion, can you mark the PR as ready?

jenkins: test this please

3ds build:

Variable width buttons no longer needed, button_width can be used in its place.

Looks good to squash and merge 馃憤馃徏
