In C++, globals initialization order accross translation units is not
defined. Accessing a global via a function ensures that it is initialized.
This will be needed for #7638, which will statically initialize change
handlers after the Options object has been initialized.
1. Moves more assets-related stuff from `init` to `engine/assets`.
2. Removes `SDL_audiolib` dependency from `soundsample.h`.
3. Cleans up some unused/missing includes.
During `ReencodeDungeonCels`, extracts floor tile foliage into
a triangle with the floor frame and a separate 16-px tall `TransparentSquare`.
This means that the floor frames are now always triangles and
the foliage can be rendered directly without masking.
Dungeon graphics sizes:
Map | Frames | Foliage frames | Byte size | Before PR | After PR
-----|--------|---------------:|-----------:|----------:|----------:
Town | 3,803 | 41 | 2,317,832 | 2,242,056 | 2,242,190
L1 | 1,119 | 11 | 738,836 | 721,604 | 721,110
L4 | 1,091 | 6 | 603,140 | 584,500 | 584,242
RG99 binary size reduced by ~4 KiB: 2,426,380 bytes -> 2,421,388 bytes
Triangles in the dungeon CEL data have two redundant 0x00 pixels every other row.
Re-encodes the dungeon CEL data to remove these pixels in order to save RAM and simplify the rendering code.
Example RAM savings:
```
VERBOSE: Re-encoding dungeon CELs: 1,119 frames, 738,836 bytes
VERBOSE: Re-encoded dungeon CELs: 1,119 frames, 722,552 bytes
```
Performance remains the same. The rendering code is now a bit simpler.
We may want to migrate this to 1 file per monster but for now the
migration is as close to the hard-coded version as possible.
Sprites that are used by multiple monsters are only loaded from disk
once.
Fully migrates debug commands to Lua and organizes them into logical
groups.
The CLI `+` syntax now runs Lua, e.g.:
```bash
build/devilutionx '+dev.player.trn.plr("infra")'
```
Chat hotkeys run Lua code if they start with `/lua`, e.g.:
```ini
[NetMsg]
QuickMessage1=/lua message(dev.player.info())
```
1. `Events` global is replaced with `require('devilutionx.events')`.
2. Table is simplified and documented.
3. `On` removed from the event names as it was a bit redundant.
4. Functions are camelCase for consistency (e.g. `add` instead of
`Add`).
Example script:
```lua
local events = require("devilutionx.events")
local render = require("devilutionx.render")
local message = require("devilutionx.message")
local function greet()
message("Hello from " .. _VERSION)
print("Hello from ", _VERSION)
end
events.GameStart.add(greet)
local function drawGreet()
render.string("Hello from " .. _VERSION, 10, 40)
end
events.GameDrawComplete.add(drawGreet)
```
Enabled only in Debug mode.
Runs Lua similar to the `lua` CLI.
Supports multiline input with Shift+Enter.
Missing features:
1. Scrollback.
2. Input history on up/down.
Open with backtick, close with Esc.
* GameMenu: Add a flag to notify that game menu is on/off
This patch adds a simple flag so other source files can see if game menu
is currently off or on.
* Automap: Don't close automap when pressing space with other windows open
Currently if we open a lot of windows and have automap enabled, and we
press space - all of the windows along with automap get closed. This
patch removes that, and allows to close automap with spacebar, but only
if every window is closed.
```lua
local render = devilutionx.render
local function drawGreet ()
render.string("Hello from " .. _VERSION, 10, 40)
end
Events.OnGameDrawComplete.Add(drawGreet)
```
