A port of Laser Hockey from Wii Play.

User guide

Project similar to tennis, move the platform to hit the ball into the opposing goal.

Controls

Stylus - move platform

Known issues

Game banner icon is still messed up.

Add touch panel code to prohibit Join/Cancel loop.

Exiting the hockey screen causes a memory leak.

Random "power shots" (Box2D), may be ok?

DS for player who exits multiplayer game does not shut off wireless hardware.

Cancel wireless codepath executes on startup? Possibly emulator only.

Paddle colors are wrong on child in multiplayer.

Ball looses a lot of vertical velocity after hitting walls eventually settling on a single Y coord.

Fast moving paddle moves through the ball.

Internal build: 0.2.0 January 5, 2008

• We have a nice looking title screen with a single button for Practice which just launches the same old game with no way out
• Added a real player two paddle

Internal build: 0.1.7 December 31, 2007

• I added the score numbers. I chose Lucida Sans Unicode for them. It sounds like the most boring font but I think it works for this game. Our art director may change this later. I also hooked the actual scores up to the sprites.
• I am finally detecting lid closes.

Internal build: 0.1.6 November 30, 2007

• The ball can now move between screens. There are actually two balls, one for each graphics engine. However, I am only checking the main ball (lower screen) for my crappy collision detection. The sprites in each screen will wrap and I am using this feature to draw the ball on the top screen when the position goes negative. The same goes for the top paddle so that I didn't have to rewrite my crappy physics methods at all. I force my paddle to be in negative world (yes, that was a Mario reference) so that my negative world ball will collide with it.
• The ball can travel through the goal. I am keeping a score up to 9 but you can't see it yet.

Internal build: 0.1.4 October 31, 2007

• A paddle appears when you touch the bottom screen. You can move it around. If you're not moving too fast, the ball will sort of bounce off of it. That is all. I might leave the physics as bad as it is for now and concentrate on sending the ball to both screens next.
• Added paddle sprite
• Hooked paddle sprite up to touch screen input
• Added some simple collision detection

Internal build: 0.1.3 September 30, 2007

• This build actually looks worse than the last one. I am dropping pretty pictures for functionality. I wanted to learn how to use the 2D graphics engines in graphics mode so I drew parts of the neon bars and the ball using a simple 16-color palette. I am now displaying the backgrounds and ball (finally a moving ball) using character and screen data however, the game is still not playable. For people without a hardware setup, I am packaging NO$GBA (a Nintendo DS emulator) with this release.
• Removed full color bitmap image so that I can use graphics mode
• Learned how to use 16x16 color palette
• Added character background for glow
• Added character background for neon
• Added spinning ball sprite

Internal build: 0.1.1 August 31, 2007

• I grabbed one side of the board from Wii Play and converted it to a DS-sized screen. I'm using both 2D engines to display the screen on the upper and lower screen. The code from my June release was not really how I would want to implement the paddle so it is not included in this build. In other words, this build just puts a picture on each screen.
