GameSpeed is a single fast-forward multiplier applied uniformly to the
whole logic clock -- overworld walking, menu navigation and battle turns
all scale together. A player who wants 4X battles but 1X overworld (so a
cutscene or NPC dialogue doesn't blur past) has no way to get both.
Splits save.options.speed into speedOverworld/speedBattle/speedMenu, each
cycling independently, with an automatic migration so an existing save's
speed choice carries over. Game.speedCategoryInStack resolves which
category is active by walking the state stack (the same idiom
wideBattleInStack/fillScaleInStack already use), so a menu opened mid-
battle inherits battle speed rather than resetting to whatever "menu"
defaults to. Adds a new core.logic_speed hook so a mod can read or
override the resolved multiplier for the current frame regardless of
which category produced it, sitting after the link-play and run-argument
overrides so neither is a seam a mod can defeat.
RFC 0007 status: Proposed.
A platform-specific launcher wrapper (a native shell embedding this engine,
owning its own UI around the game window) needs to pause the simulation
while its own UI is on top, live-reload options it wrote outside any Lua
UI, and veto main.lua's "closing the window returns to the Lua launcher"
behavior when it owns that job itself. Implementing this by hand-patching
main.lua's love.update/love.quit directly ties every such integration to
editing the one file every other engine change also touches, guaranteeing
merge conflicts. No existing hook covers "should the per-frame simulation
step run" or "should closing the window return to the Lua launcher."
Adds two generic, additive hooks (src/core/PlatformHooks.lua): core.update
and core.quit_to_launcher, replacing what would otherwise be inline
main.lua special-casing. Also adds Manifest.force_enable_env, letting a
mod that cannot function disabled on the one build where its env var is
set (a platform-bridge mod bundled only with that build) re-enable itself
regardless of a saved disable.
RFC 0006 status: Proposed.
Expose a generic seam so a mod can drive a second screen without the
engine owning any dual-screen layout policy:
- render.compose hook in Renderer:endFrame hands a mod the finished
world + UI canvases, their SGB zones, the frame metrics,
Renderer:blitCanvas (lifted from the internal blit closure) and the
SecondScreen bridge. Return true to take over the window; no wrap (or
calling next) runs the normal single-window composite byte-for-byte.
- SecondScreen.lua + the Android Presentation bridge (love_android_
secondary_* in common/android.cpp, GameActivity secondary display)
as the optional physical-second-display transport.
No battle-render changes: a mod lays out the two screens (including any
battle split) itself. Ships with a unit test, no-mod parity via
gate_hooks, and docs/modding.md (D14).
