Mouse/touch support #634
Description
This is mostly a wishlist meta-issue proposal and opened for discussion.
Touch-only devices are not working at all without keys (except current Android on screen buttons native implementation). To bring basic interface support without on screen buttons, the RPG Maker MV HTML5 game demo shows some guidelines about getting a discreet, zero-configuration way to add "decision" and "cancel" and movement by targeting a map tile without arrows or buttons on the screen.
Of course, extra keys are still needed for lots of games, but basic movement with decision/cancel support may help as a good start without needing to create new portable configuration scenes yet, which requires some SDL mouse/touch code in the app first.
Proposed features, based on the RPG Maker MV behaviour:
- 1st mouse button (usually left click) and 1 finger tap to work as decision key
- 2nd mouse button (usually right click) and 2 fingers tap to work as cancel key (example)
- Click / tap over a Window_Item from to select them in a Window_Selectable
- Tile click/touch for tiles, path finding and generate arrow keypresses to follow the route found (Zegeri's example).
Some facts:
- Esc/X (Cancel key) acts on message windows waiting for keypress in RPG Maker MV as usual.
- Any tap, with one or two finger are advancing window messages too. However, when RPG Maker MV is showing window selectables, two finger tap seems to cancel and opens the game menu in the same action.
- 2nd mouse button click does not act as cancel in window messages.
Extras:
- Power Mode patch supports mouse with 0002:MCOORDX and 0003:MCOORDY. Maybe is worth to make these games compatible, depending on usage popularity.
