1 | # Soundboard
2 |
3 | Very simple library to load and play sounds with Web Audio API.
4 |
5 | This is not an official Google product.
6 |
7 | #### How to use ####
8 | Include the script in your project:
9 | ```html
10 |
11 | ```
12 | Define a new instance of `Soundboard`, providing an array of sources ( `'sound_id': 'path/to/file_without_extension'` ):
13 | ```js
14 | let soundboard = new SoundBoard({
15 | 'ok': 'sounds/ok',
16 | 'error': 'sounds/error'
17 | });
18 | ```
19 | Soundboard will look for the filenames, load them using an .mp3 or .ogg extension depending on the browser playback support, and map them to the specified sound_id.
20 |
21 | To play back the sound when needed, just use `.play( sound_id )`:
22 | ```js
23 | soundboard.play( 'ok' );
24 | ```

1 | # THREE.TextTexture
2 |
3 | A wrapper of THREE.CanvasTexture to easily draw text, used for setting up UIs in VR quickly.
4 |
5 | This is not an official Google product.
6 |
7 | #### How to use ####
8 | Include the script in your project after `three.js` has been included:
9 | ```html
10 |
11 |
12 | ```
13 | Create a Text object passing your WebGLRenderer instance, width and height of the resulting texture:
14 | ```js
15 | let text = new Text( renderer, 1024, 512 );
16 | scene.add( text.mesh );
17 | ```
18 | Add the mesh object to your scene, that will add a plane mesh to your scene with the aspect ratio of the specified dimensions.
19 |
20 | Set text whenever you need an update by using Text.set( sentences ):
21 | ```js
22 | // sentences can be a single sentence
23 | text.set( 'hello world' );
24 |
25 | // or an array of sentences that will act as multiline
26 | text.set( [ 'hello', 'there,', 'world' ] );
27 | ```
28 | Text has a built-in text-splitting mechanism that will prevent lines from being cut horizontally.
29 | #### Changing styles ####
30 | The text uses a white 50px Robot font with some drop shadow effect. Make sure you include in your HTML the fontface you want to use.
31 | To change style or effects, you'll have to change the code Text.set.

--------------------------------------------------------------------------------
1 | # Twixt
2 |
3 | A very straightforward tweening library, with Promises.
4 |
5 | This is not an official Google product.
6 |
7 | #### How to use ####
8 | Include the script in your project:
9 | ```html
10 |
11 | ```
12 | This will create a global **Twixt** object.
13 |
14 | You can create twixted values by using `Twixt.create`:
15 | ```js
16 | // Twixt.create takes an initial value and an easing mode
17 | let a = Twixt.create( 0, 'Linear' );
18 | let b = Twixt.create( 100, 'InOutQuint' );
19 | ```
20 | From there, you can tween to any value by using .to():
21 | ```js
22 | // a goes to 1 in 100ms in a Linear tween
23 | a.to( 1, 100 );
24 |
25 | // b goes to 0 in 500ms using InOutQuint tween after a delay of 100ms
26 | b.to( 0, 500, 'InOutQuint', 100 )
27 | ```
28 | Twixt values' `.to()` method returns a promise, so you can chain events or do something when the tween is completed:
29 | ```js
30 | a.to( 0, 100 ).then( () => {
31 | b.to( 100, 200 ).then( () => {
32 | console.log( 'done!' );
33 | });
34 | });
35 | ```
36 | You can delete tweened values by calling `Twixt.destroy`:
37 | ```
38 | Twixt.destroy( a );
39 | ```
40 | #### Auto updated
41 | Twixt will autoupdate using its own `window.requestAnimationFrame` unless you specify `Twixt.autoUpdate = false;`. In that case, you have to update it manually by calling `Twixt.update();` from inside your animation loop.
42 | #### Available tweening equations
43 | There's only Linear, and In, Out and InOutQuint for now

86 | or contributory patent infringement, then any patent licenses
87 | granted to You under this License for that Work shall terminate
88 | as of the date such litigation is filed.
89 |
90 | 4. Redistribution. You may reproduce and distribute copies of the
91 | Work or Derivative Works thereof in any medium, with or without

115 | within a display generated by the Derivative Works, if and
116 | wherever such third-party notices normally appear. The contents
117 | of the NOTICE file are for informational purposes only and
118 | do not modify the License. You may add Your own attribution
119 | notices within Derivative Works that You distribute, alongside
120 | or as an addendum to the NOTICE text from the Work, provided
121 | that such additional attribution notices cannot be construed
122 | as modifying the License.

138 |
139 | 6. Trademarks. This License does not grant permission to use the trade
140 | names, trademarks, service marks, or product names of the Licensor,
141 | except as required for reasonable and customary use in describing the
142 | origin of the Work and reproducing the content of the NOTICE file.
143 |
144 | 7. Disclaimer of Warranty. Unless required by applicable law or
145 | agreed to in writing, Licensor provides the Work (and each
146 | Contributor provides its Contributions) on an "AS IS" BASIS,
147 | WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or

157 | negligent acts) or agreed to in writing, shall any Contributor be
158 | liable to You for damages, including any direct, indirect, special,
159 | incidental, or consequential damages of any character arising as a
160 | result of this License or out of the use or inability to use the
161 | Work (including but not limited to damages for loss of goodwill,
162 | work stoppage, computer failure or malfunction, or any and all
163 | other commercial damages or losses), even if such Contributor
164 | has been advised of the possibility of such damages.
165 |
166 | 9. Accepting Warranty or Additional Liability. While redistributing
167 | the Work or Derivative Works thereof, You may choose to offer,
168 | and charge a fee for, acceptance of support, warranty, indemnity,
169 | or other liability obligations and/or rights consistent with this
170 | License. However, in accepting such obligations, You may act only
171 | on Your own behalf and on Your sole responsibility, not on behalf
172 | of any other Contributor, and only if You agree to indemnify,
173 | defend, and hold each Contributor harmless for any liability
174 | incurred by, or claims asserted against, such Contributor by reason
175 | of your accepting any such warranty or additional liability.
