Shape - Arc Options
The Arc Options dialog defines the radial geometry of vector arc shapes in Total Launcher. Unlike standard shapes with fixed bounds, arcs are plotted along a circular perimeter using an angular starting origin and a clockwise rotational sweep.
Dialog selections are discussed below the image. To navigate to an item, select it in the Shape - Arc Options image. If NOT selecting any item and wanting to return to the prior page: swipe right-to-left; use the browser’s ‘back’ arrow; or use the Wiki’s Backlink icon

Shape - Arc Options dialog. Make selection above.
The navigable elements in this demo dialog are:
- Cancel / OK: Tap Cancel to discard changes or OK to commit the arc configuration to the shape resource. Both will return the user to the Arc Add dialog to continue with other arc modifications
The other elements in this demo dialog are discussed below:
- Start angle: Defines the starting radial coordinate along the circular perimeter. Total Launcher anchors 0° at 3 o'clock (the positive horizontal axis) and advances clockwise around the center pivot.
- Start angle value 0° (Pill Badge): Tap the badge to open an on-screen numeric keypad and input an exact degree integer (`0°` to `360°`).
- Start Angle Slider & Step Buttons (- / +): Drag the horizontal slider or tap the minus/plus buttons to adjust the starting angle incrementally.
- Sweep angle: Defines the rotational length of the arc segment extending clockwise from the designated Start Angle (`1°` to `359°`).
- Sweep angle value 90° (Pill Badge): Tap the blue pill badge to enter an exact sweep angle via numeric keypad.
- Sweep Angle Slider & Step Buttons (- / +): Drag the slider or tap minus/plus buttons to adjust the angular span.
⚠️ The Coordinate Challenge: 12 o'clock vs. 3 o'clock
In design intuition, most creators envision an arc like a clock face with 12 o'clock as the natural top (0°). Because Total Launcher's coordinate system anchors 0° at 3 o'clock, configuring arcs from the top requires angular conversion:
Total Launcher Start Angle = (Clock Face Angle - 90° + 360°) mod 360

Quick Reference: Clock Position to Total Launcher Input
Use this table as a quick reference guide to achieve common clock-oriented shapes in Total Launcher:
| Intended Visual Arc | Clock Face Position | TL Start Angle | TL Sweep Angle | Resulting Shape Profile |
|---|---|---|---|---|
| Top Quarter (12 to 3) | Start 12:00 (0°) | `270°` | `+90°` | Top-right quadrant wedge / gauge |
| Top Half (9 to 3) | Start 9:00 (270°) | `180°` | `+180°` | Upper speedometer / dome arc |
| Bottom Half (3 to 9) | Start 3:00 (90°) | `0°` | `+180°` | Lower smile / inverted semicircular tray |
| Right Half (12 to 6) | Start 12:00 (0°) | `270°` | `+180°` | Right sidebar vertical arc container |
| Full Circle Gauge | Start 12:00 (0°) | `270°` | `+359°` | Circular progress ring (leaving 1° gap) |
