Object class has hooks to implement string rendering instead of array of lines.

The strings should be rendered scaled and rotated just like any object.

Maybe theta should rotate around x instead of z.

Enemies need to have a concept of health or shields, so it takes multiple hits to destroy.

If new start point of next line in image is the same as the the last end point, we already calculated the rotate/scale/etc. so we can just use it!

This ticket is just for the creation of the character set.

I think we can get away with just capital letters A-Z, 0-9, and a few punctuation marks (like period, comma, exclamation point)

Import new svg and img header

I have no way of testing fonts at the current time.

Weapons:

• Lasers - B_BUTTON
• Plasma cannon - A_BUTTON
  (Should be rechargeable like EVADE )

Only stars render

Bullets should collide with enemies and the enemies should explode!

Let's try to make another instructional insert like the prior art. @jaymesjones, please work on setting up whatever milestones are required to get this printed and delivered NLT 12/13/2017.

Implement Font class to render vector font to the screen.

Remove reliance on Print class.

Bosses

• 3 types
• Last boss larger than the screen,
• Targeted spots on enemies/bosses to do damage / blow off parts

Score to be counted similar to EVADE 1
Travel, enemy hits, enemy deaths.
Score to be presented at the end of the game

Remove arduboy.nextFrame() call.
- Savings 160 bytes.
- Don't know if this is really needed, given all the processing we're doing.
- Files affected:
- evade.ino
- Change:
- Comment out:
// if (!(arduboy.nextFrame()))
// return;

Enemies

• 3 types
• 1 type of enemy projectile --- Laser

Add bullet firing logic

Should show points earned and a "Try again" message.

Power and health and that sort of thing really belong in the Player class.

Player is currently not written as a class, but it could be expressed as one.

Likely enemies and bullets should be classes, too.

This will be an on-going task until we get to production and will me marking PRs against this.

All Music and SFX will leverage the Sound Class that @mschwartz created.

EEPROM

Render Object as a vector object, per Jay's tool output

Controls:

• UP_BUTTON == “Nose down” == Playfield go up, ship travels down
• DOWN_BUTTON == “Nose up” == Playfield go down, ship travels up.
• A_BUTTON (left-most red button) == “Fire rechargeable plasma cannon”
• B_BUTTON (right-most red button) == “Fire repeatable laser”

Make the LEDs do something

There's no benefit to generating hex values inside the image data. The hex is actually much harder to read, and all the values are ones we care to read as decimals.

Also, the compiler generates warnings for the conversions since 0xff is both -1 and 255 and 255 doesn't fit into a signed byte!

Convert all usages of float to fixed point. Implement fixed point math routines. Implement sin/cos lookup table for fixed point maths.

Any numbers we keep internally that need to be displayed on screen should be done as BCD. We would need a BCD class that knows how to add and subtract and render.

We can make an evade/img directory and then:

#include "img/whatever.h"

This will allow us to keep all those image .h files out of the main directory.

We might be able to just use Arduboy2Core class. We'd have to implement our own sBuffer and our own drawImage methods.

The amount of RAM savings is unknown at this point. We may have a performance boost as well as code savings.

B button is afterburner.

Afterburner consumes energy.

When energy is empty, afterburner stops working.

Maybe power up you shoot or crash into that gives you more energy?

Energy slowly regenerates.

Z currently a word, so we have 16M or so before the universe wraps and we get some rounding errors.

Making Z a float will greatly increase the range before wrap. Probably to a point we'll never ever see it unless we leave the game running for days and we don't have some level ending logic.

Handle controls, move camera, render hud, deal with resources, etc.

Enemies need to shoot!

Play, audio on/off setting
Shows EVADE 2 art.

1. We need a STFU call to quiet everything.
2. Music needs to loop.
3. We need a stop music call.
4. It would be nice to be able to have a function called when music is complete
5. It would be nice to be able to have a function called when sound effect is complete.
