Stream 11/3/2019 - Github Actions and Reversing Gravity

Check Out the Stream @ https://twitch.tv/talk2megooseman

Had a great and fun stream today! Started it off fixing my Github Action and then learning about the new caching feature in Github Actions so dont have to re-install packages. After knocking that stuff I next started the adventure of doing reverse gravity command.

• Github Actions yarn install issue
  • Here is the error I am seeing https://github.com/talk2MeGooseman/twitch-interactive-overlay/commit/6df712ab7becea20f77b855853670fbd3e3bb00c/checks?check_suite_id=292549368
  • Removing Borales/actions-yarn@master since Yarn is already installed in the env now
    • Example of caching the yarn install

            steps:
                - uses: actions/checkout@master
                - name: Cache node modules
                  uses: actions/cache@preview
                  with:
                    path: node_modules
                    key: ${{ runner.os }}-node-${{ hashFiles('**/yarn.lock') }}
                    restore-keys: |
                      ${{ runner.os }}-node-

                - name: yarn install
                  if: steps.cache.outputs.cache-hit != 'true'
                  run: |
                    yarn install

• Reverse gravity command in Phaser.io
  • We can set the gravity via scene.physics.world.gravity.y = -400
  • Need to update the math for our sprite animations and position because its assuming a positive gravity so all the commands will look just wrong
  • Tweak the logic in the UserSprite to changes the Y velocities if the gravity is flipped. But the same logic has to be spread to the other sprites the spawn on the screen. So decided to finally make a base class to have some base logic instead of just defaulting to user helper module.
  • Will need to finish doing the refactoring and switch the various sprite classes to use the new BaseSprite class
