Pool by Devin Gray

pool's Issues

Add cue stick animation based on velocity

Currently the cue stick is visible during aiming. When the shot is fired the cue ball immediately has velocity and the cue stick disappears. This ticket to add a nice animation after the shot is hit that shows the cue stick go back (based on the amount of velocity selected) then forward, imparting velocity onto the cue ball.

Show the path of the object ball's next path

Would be sweet to see how the cue ball would collide with the object ball and where that object ball would travel.

Make the cue ball roll properly

Currently the cue ball moves by sliding. This ticket could make the cue ball actually "roll" by positioning the red dots accurately as it rolls.

Make a snooker option

This would require some work, in conjunction with the ability to play a 9 ball game. This ticket would expose a new option to switch racks

8 Ball
Snooker

Snooker requires a bunch of new but smaller balls and changes the pocket sizes too...

After fouling allow user to place cue ball

When the cue ball scratches it is placed automatically... Have the user be able to place the ball in hand anywhere on the table.

Move horizontal power bar to the left side and make vertical

In an effort to make the game fit only on 1 screen (no horizontal or vertical scroll bars), this ticket could move around the power bar to the left side and make it vertical. Lets see how we can get the screen to be as simple as possible.

Experiment with 3D rendering for the cue and object balls

Currently the graphics are all 2D. This experimental PR could demonstrate how to render 3D balls via HTML/Javascript + some other graphing library (Open GL, etc...)

Make ball stop when reset due to falling in hole

When ball enters hole and resets position, it keeps rolling if there's still momentum left from last shot.

Don't allow a shot until all balls are stationary

Currently you can see the cue stick while the other balls are still moving. To see this fire the cue ball at the rack and notice the stick shows up while other balls move around.

Add a HOWTO play the game page

There are no instructions on how to play (use the keyboard to fire the ball, select your x/y location of the cue, and the power...)

Add a favicon logo for the browser tab

There is no favico logo for this pool game. This ticket will add one (that is pool related).

Adjust sound(s) volume based on impact energy

When the ball is potted (and soon when other sounds are added) it is set to a static value. This ticket could introduce variable sound volume based on impact energy. Faster collisions == louder

3D Ball rendering

Currently the balls are rendered on a 2D plane. We could make this much better to render in 3D. Perhaps use an existing 3D library.

Scope of this ticket could be a proof of concept new 8 ball that rolls...

Improve ball collisions

There are a few ways to cause odd collisions. This ticket will track improving the main collision detecting and resolution functions.

Split out source code from main index.html into various javascript files

To improve development, this ticket could split out the main index.html file's various javascript functions into separate javascript files.

Add ability to aim the cue by dragging the mouse

Currently you have to click a specific spot for the cue ball to be in order to aim. This ticket could add the ability to drag and move this "ghost" ball around using the mouse.

I dont know

Becarefull, maybe it's a trap!

Add sound effects (pool ball colliding, pool ball going into pocket)

Would be cool to have sound effects during collisions or when balls are potted.

Create animation of the potted balls sliding down the rail

Currently when a ball is potted, it immediattely shows up in the rail (on the right side). It would be slick to have an animation showing the ball "sliding down the rail" to its spot.

Improve collisions with the rail and pocket corners

Currently there is no collision support for the pocket corners. This ticket could improve how the ball behaves when it strikes these points on the side pockets

Make all balls stop faster - i.e. increase friction

Currently there is an annoying delay for all the balls to become stationary (which is a new feature to prevent shots until all balls stop), but this makes for some waiting.

This ticket could tweak the value of table friction to a more playable value.

Add a simple mute button to suppress sounds

Add a simple mute button to suppress sounds

Track who is shooting (solids vs stripes)

Implement some additional rules of pool.

Track who is shooting, if they are solid/stripes, and if they hit the wrong ball first cause a foul to occur.

Initial fast cue ball

The cue ball moves at an ultra-high speed that causes many strange collisions when the player does not aim for the first shot.

Add ability to change color of the felt

Currently the felt color is statically defined (green). This ticket could add the ability for a user to change the felt color (maybe using a defined list, or ideally some color picker).

Add a Robot AI to play against

Currently this is a 1 player toy game... This ticket could add a robot to play against.

Change max ball velocity to a more reasonable level

Ball velocity resets to 50 after firing and also occasionally refuses to shoot the ball. Unsure how to recreate the issue, but it might affect all devices. More testing would need to be done.

Add MIT license

Add MIT license

Add ability to play against another human player

Add ability to play against another human player. Keep track of scores, who shoots next, etc...

Add README.md

Add a README.md file to describe this repo and how to develop.

Change bumper collisions to account for rubber

Currently the bumper collisions are treated as elastic collisions just like striking a mirror.

        ball = this.balls[i];
        //if potted, no collision with bumper
        if(!ball.potted) {
            if(ball.position.x > X_MAX-PREFS.bumperWidth-ball.radius || ball.position.x < 0+PREFS.bumperWidth+ball.radius) {
                    ball.velocity.x *= -1;
            }
            if(ball.position.y > Y_MAX-PREFS.bumperWidth-ball.radius || ball.position.y < 0+PREFS.bumperWidth+ball.radius) {
                    ball.velocity.y *= -1;
            }
        }
        ball.update();

Note the velocity is simply flipped. We should account for some velocity decrease after striking the rubber bumper. Also make this rubber bounce be a preference.

Add a link to the sleddog/pool github page

Add a link to the sleddog/pool github page on the bottom right hand area of the application.

Add properties panel and initial settings

There are a number of constants and settings that would be nice to expose in some type of properties panel.

Felt color
bumper color
Max velocity
Friction / max constants
etc...

Add a simple dialog that allows the user to set these, and setup for future settings to be added.

Add a 9 ball rack

Currently the game defaults to 8 ball. This ticket could simply have the game load a nine ball rack as opposed to the 8 ball rack

Implement initial 8 ball rules and two player mode

It is time... We need 8 ball rules and two player mode.

Add a cue stick

Currently there is no cue stick. This ticket could introduce a cue stick to the UI.

Bring back the space key to fire the cue ball

We now have a cool power slider on the left side, but you have to use the mouse to fire the shot. This ticket could bring back the keyboard to "power up" the shot.

The longer you hold the keyboard, the stronger the shot will be (until it maxes out).
A quick press, will be a slow shot
A long hold and release, will be a power shot

Add a POWER bar for shot strength

Currently there is no clear power bar for how hard the cue ball is hit. This ticket could add this ability.
