I'll be using this to make a sparkling effect on the debris field left
behind from a destroyed ship.
It can also be used to do the temporary invincibility effect when
(re)spawning the player.
Closes#23: Main menu's start button doesn't run the get-ready timer
I made the start button go directly to `GameState::Playing`, which is
not actually the right state for beginning a new game. Swap the states
and everything works again.
There is now a `Weapon` component which is just a timer for the gun's
fire rate. It is ticked every frame, clamping at the "ready" state (0
time remaining).
The ship spawns with this thing, and the `input_ship_shoot` system has
been updated to use it.
Now it works!... but it runs every single frame, probably causing a
bunch of unnecessary text rendering and UI layout operations. I'll have
to come back and make it event-based at some point.
The `rand` crate eventually depends on `getrandom` which requires a
different feature set when running in the browser. WASM has no OS, and
so no RNG provider... but the browser, specifically, has one that the
JavaScript runtime can touch. Enabling the "wasm_js" feature on
`getrandom` allowes it to use this backend.
An extra config option must *also* be passed to `rustc`. THis can be set
through the environment, or the config.toml. I've chosen the latter so I
don't need to think about it very often.
I marked 0.2 at some point, so I guess I should keep incrementing this
during development. The menus are finished, which is as good a
checkpoint as any.
I've taken a lot directly from the Bevy UI button example.
(https://bevy.org/examples/ui-user-interface/button/)
I'll make it look better later. For now, it just needs to exist. Onward
to the UI operation system!
I want the different "scenes" to be their own plugins for ease of setup
and reading.
The main menu plugin has been renamed to have "Plugin" first. This is so
the lexical sort in the docs places all the plugins next to each other.
The "get-ready" plugin has been given an empty struct and an
`impl Plugin` to match the main menu plugin. I've started the game over
scene, but left it unimplemented.
Closes#16
Bevy provides Deref and DerefMut derives, so that's nice. I'm not sure
it makes any sense to keep the field private since those derefs expose
the Vec2 anyway. I added an `impl Default` anyway, though.
The non-gameplay scenes are really just a bunch of widgets. I'm going to
put them all together and then bundle the functionality with some
exported plugin builders.
I'm not sold on the name, but anyway.
This module will hold the systems that power the main game mechanics, as
well as a few extra items to support that (in particular, the Lifetime
component).
The player will be respawned, their lives decreased, and the board
cleared. The UI doesn't update, and the sudden snap to a freshly reset
board is quite jarring. The state transition to GameOver stops the game,
but there isn't anything else running in that state so it just looks
frozen.
Basically, there's a ton left to do, but technically I have handled
player ship destruction!
