Todo and Idea List for Tennix
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

See the file "HACKING" for help finding your way around the tennix source.

HIGH-PRIORITY

 1. Proper collision detection for ball <-> racket
    (Different sound + random movement when edge hit)
    Maybe: make racket less visible until power value is reached
 7. Allow navigating menu with joystick / keyboard in addition to
    mouse ("cursor" state that is modified instead of directly
    using the mouse my mx coordinates)
 8. Flip coin to determine which player serves
    (Using the Animation framework + some inkscape'd pictures)

LOW-PRIORITY

 2. Give a visual clue where the ball goes when serving (blinking)
    (Only when power reaches a certain level)
 5. Rain moves ball in the negative direction (z -= RAINSPEED)
 6. Reduce current "power" value when moving in Y direction
 9. Retrieve the ball when it goes offscreen or into the net
    (Either via Balljunge mode, long referee hand or "hand of god")


==================================================================
ANIMATION FRAMEWORK
==================================================================

             FROM --------------> TO
               position (grav+x/y)
                       zoom
                     rotation
                    opacity (??)


               + "tween functions" (sin, 1-p, exp, ...)

==================================================================
MENU AND NAVIGATION (COSMETIC)
==================================================================

 -> Make options menu same style as main menu
 -> add picture to left side of main menu
 -> NICE TO HAVE:
    Physikalischer Tennis-ball im Hauptmenü zum herumspielen

==================================================================
PHYSICAL PROPERTIES
==================================================================

GROUND
  * Restitution

RACKET
  * Restitution
  * "power"?

BALL
  * (maximum) Speed (or: speed curve)
  * Restitution
  * Elasticity (???)

==================================================================
PARTY MODE AND INPUT ISSUES
==================================================================

Input selection like Fifa 96 (left / right)
Proper gamepad axis support (can we do this in general?)
Tournament config / setup / frontend (GTK+/Qt/[...]?)

read keyboard input mappings from config file and generate bindings
dynamically or even allow new bindings configured in the UI


==================================================================
CAREER MODE
==================================================================

  * Ball + racket buying/selling/upgrading
  * Schläger: upgrades [name, verbesserung, kosten, haltbarkeit]
  * Person, Training: Laufgeschwindigkeit, Vorhand/Rückhand
  * add wear (abnutzung) to ball and racket, so one has to buy new
    stuff every now and then ("design charge" vs "current charge")


==================================================================
LOCATIONS
==================================================================

  * Weather-verlauf pro location gegeben über W-vtlg. mit anschl.
    berechnung des wetterverlaufs über simulierte stichprobe


==================================================================
IN-GAME FX
==================================================================

 * Grafische Darstellung der hit points des Balles am Ground
 * Wind (modifies the ball movement)
   Wind darstellen über die rot-weiße "Windfahne"
 * Snow (christmas edition?)
 * Sunshine (=current, normal behaviour)

Schiri spannt Schirm auf, wenns es regnet

Shadow computer-generiert?? (und für schläger zusätzlich?)
Shadow x2/x4 wenn Nacht-Modus (weil scheinwerfer!!)

Kleinere Schläger, dafür mehr Sprites für die Animation
Schläger einfärben per SDL möglich? (HUE-verschiebung)

Sound effect groups: Group the same types of sounds (e.g. voice,
racket, ground) in one sound "GROUP" that shares a channel.

Trainings-Modus mit Zielscheibe

Möglichkeit, ans netz zu gehen, aber dann kann man sich nur mehr
einen kleine bereich auf- und abbewegen (by mario).

==================================================================
TECHNICAL DETAILS
==================================================================

librsvg for rendering the SVG source files in-game instead of
shipping pre-rendered PNG files (would allow us to modify XML)

"Satz vom sportlichen Statistiker" (add statistics features to AI)

Garbage collector für c/c++?

umsteigen auf c++?

Clip rectangles and image blits to visible screen area

MAEMO WISHLIST
~~~~~~~~~~~~~~
Fix sounds (wav, mp3? - ogg doesn't seem to be supported)
Widescreen support - 800x480 (make "outer areas" input-accepting)


Brainstorming
~~~~~~~~~~~~~
Make sound deactivatable (or sound volume settings?)
User-settable "sets to win" (2 or 3)
Highscore list
Setting player names
Change between full screen and windowed mode in Windows
Implement tie break
Implement "hit in the right area on serving"
Correct serve repeat when serving into the out
