twang-mp/TWANG32/TWANG32.ino
per1234 840eab60aa Move sketch to appropriately named subfolder 
The Arduino IDE requires that a sketch be located in a folder of the same name. Although the name of the repository does match the sketch name, when GitHub's popular Clone or download > Download ZIP feature is used to download the contents of a repository the branch/release/commit name is appended to the folder name, causing a mismatch.

When opening a file that does not meet this sketch/folder name matching requirement the Arduino IDE presents a dialog:

The file "TWANG32.ino" needs to be inside a sketch folder named "TWANG32".
Create this folder, move the file, and continue?

After clicking "OK" the Arduino IDE currently moves only the file TWANG32.ino to the new folder, leaving behind the other source files. This causes compilation of the sketch to fail:

TWANG32-master\TWANG32\TWANG32.ino:30:23: fatal error: twang_mpu.h: No such file or directory

TWANG32 - An ESP32 port of TWANG
(c) B. Dring 3/2018
License: Creative Commons 4.0 Attribution - Share Alike
TWANG was originally created by Critters
https://github.com/Critters/TWANG
It was inspired by Robin Baumgarten's Line Wobbler Game
Recent Changes
- fixed bug in settings when initial read failed. It was
trying to turn off the sound timer while it was still NULL
- Number of LEDs is now adjustable via serial and wifi. Woot, no
recompile just to change strip length.
- A little refactoring so Wifi and Serial interfaces can share
some code.
- Added Refresh button to web page

/* ==== Level Editing Guide ===============
Level creation is done by adding to or editing the switch statement below
You can add as many levels as you want but you must have a "case"
for each level. The case numbers must start at 0 and go up without skipping any numbers.
Don't edit case 0 or the last (boss) level. They are special cases and editing them could
break the code.
TWANG uses a virtual 1000 LED grid. It will then scale that number to your strip, so if you
want something in the middle of your strip use the number 500. Consider the size of your strip
when adding features. All time values are specified in milliseconds (1/1000 of a second)
You can add any of the following features.
Enemies: You add up to 10 enemies with the spawnEnemy(...) functions.
spawnEnemy(position, direction, speed, wobble);
position: Where the enemy starts
direction: If it moves, what direction does it go 0=down, 1=away
speed: How fast does it move. Typically 1 to 4.
wobble: 0=regular movement, 1=bouncing back and forth use the speed value
to set the length of the wobble.
Spawn Pools: This generates and endless source of new enemies. 2 pools max
spawnPool[index].Spawn(position, rate, speed, direction, activate);
index: You can have up to 2 pools, use an index of 0 for the first and 1 for the second.
position: The location the enemies with be generated from.
rate: The time in milliseconds between each new enemy
speed: How fast they move. Typically 1 to 4.
direction: Directions they go 0=down, 1=away
activate: The delay in milliseconds before the first enemy
Lava: You can create 4 pools of lava.
spawnLava(left, right, ontime, offtime, offset, state);
left: the lower end of the lava pool
right: the upper end of the lava pool
ontime: How long the lave stays on.
offset: the delay before the first switch
state: does it start on or off
Conveyor: You can create 2 conveyors.
spawnConveyor(startPoint, endPoint, direction)
startPoint: The close end of the conveyor
endPoint: The far end of the conveyor
direction(speed): positive = away, negative = towards you (must be less than +/- player speed)
===== Other things you can adjust per level ================
Player Start position:
playerPosition = xxx;
The size of the TWANG attack
attack_width = xxx;
