An app that mirrors your phone to your compute and maps controller input to the screen

Changes in this release:

• Fixes for UI jankiness (e.g. locking up, nicer shutdown behavior).
• 'Minitouch' optionally allows for sending Controller Input directly to the phone instead of through the mouse. It should be slightly lower latency and more accurate, but it has a bit of a startup time.

Hotfix (1.04):

• Fix an issue where rolls were snapping to corners,
• Fix an issue where the 'drag region' was too large.

User-facing changes in this release:

• The debug button (e.g. the right trigger) can now be used to hot reload the posiitons.json. You can now edit the touch data without closing and reopening Dragalia Control. There's also a bunch of logging for it,
• The right bumper can now be used to force strike.
• Improve handling rapid movements, esp change in direction. Remember to turn off Quick Turn in game.
• Improve deadzone handling.
• Fix an issue where skills weren't being activated if they were pressed too quickly.

THERE WAS A HOTFIX. Download the updated build below.

What is this?

The first version of "Dragalia Control":

• Detects Android devices and launches an instance of SCRCPY to show the device screen on their PC.
• Reads controller input from a XBox-like controller and forwards them to the SCRCPY window as useful Dragalia Lost input.

See it in action on YouTube: https://youtu.be/Jt_tPyQo_gA

This targets Windows 10, 64-bit. The buttons are mapped for the Galaxy S9 and Galaxy S10 Plus. For other devices, see the 'What if my device isn't supported?' section.

Since this uses SCRCPY, the requirements are the same. See https://github.com/Genymobile/scrcpy#requirements. This is not optional.

You really want quick turn off (180 and 90).

How to use it

1. Follow the instructions to enable ADB debugging from https://github.com/Genymobile/scrcpy#requirements. There are a few videos on this as well: https://www.youtube.com/results?search_query=set+up+scrcpy
2. Download "dragalia_control.zip" from below.
3. Unzip it somewhere.
4. Open Dragalia Lost on your phone. Yes it needs to be open first.
5. Run "dragalia_control.exe" from the place you unzipped it.
6. You'll probably get a prompt on your phone asking you to 'authorize your pc'. Accept.
7. A very ugly UI should appear with a dropdown list of phones. If you only have one phone, press 'Start'.
8. It will take a few seconds to start up, but you should see your phone screen in a SCRCPY window.
9. Pressing your controller buttons should move your mouse around.
10. Drop into a level and go nuts. Button mappings are described in 'What are the button mappings?' below.

What if my device isn't supported?

You'll want to take screenshots of the game on your phone (Ideally, a normal quest and the skill share menu in Kaleidoscope).

Then you can edit the positions.json file to add support for your device. You can edit an existing entry like this one:

    "2.111": {
        "NOTE": "Galaxy s10+; 1440x3040",
        "C1": [116,260],
        "C2": [116,410],
        "C3": [116,581],
        "C4": [116,725],
        "CENTER": [720,1520],
        "DRAGON": [200,2259],
        "KSS1": [288,1944],
        "KSS2": [586,1944],
        "KSS3": [853,1944],
        "KSS4": [1173,1944],
        "KSS5": [288,2245],
        "KSS6": [586,2245],
        "KSS7": [853,2245],
        "KSS8": [1173,2245],
        "MENU": [1346,234],
        "S1": [512,2601],
        "S2": [800,2601],
        "S3": [1040,2601],
        "S4": [1266,2601],
        "w": 1440,
        "h": 3040
    },

Replace "2.111" with your screen ratio, rounded to three decimal places. If you launch 'dragalia_control.exe' with your device attached, you'll see it there.

Then you want to update 'w' and 'h' to be the width and height of your screenshots.

The rest of the values are coordinate locations. It's the distance from the top left corner to the point on the screen (so, you'll notice that the "MENU" has a high X value and a low Y value; the high X is because it's very far from the left of the screen and the low Y is because it's very close to the top of the screen). I used IrfanView to do these measurements, but it should be possible in any image editor.

The entries "C1", "C2"... are character slots. The buttons on the top left of the screen for switching characters. The entries "S1", "S2"... are skill slots, at the bottom of the screen. The entries "KSS1", "KSS2"... are the skill shares in Kaleidoscope. 1-4 are the top row. 5-8 are the bottom row.

If you end up adding another device successfully, do get in contact with me either here, on youtube or on reddit, I'd be happy to add the position data to the next release.

What are the button mappings?

The left stick is for movement. Pressing down quickly will attack. Pressing down for a long time will force strike. The right stick is for rolling. Flicking the stick quickly will result in a roll. Pressing down will trigger the dragon transformation.

The face buttons (XYAB) are mapped to skills in order (e.g. X = s1, Y = s2, A = s3, B = s4). When the left shoulder bumper and the left shoulder trigger are held together, these buttons change to switch characters. When only the left shoulder bumper is held, these buttons change to the top row of the Kaleidoscope skill shares. When only the left shoulder trigger is held, these buttons change to the bottom row of the Kaleidoscope skill shares.

The Start and Back buttons both map to the Menu button in game. The right shoulder bumper is for basic attacks. You cannot hold it down to forcestrike. The right shoulder trigger is a debug button. Press it if you've moved the SCRCPY window or if it's otherwise behaving poorly.
