/* ==== 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_dir
Conveyor: You can create 2 conveyors.
spawnConveyor(startPoint, endPoint, speed)
startPoint: The close end of the conveyor
endPoint: The far end of the conveyor
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;
