P5

  • CTRL + / = Commenting in SublimetText
  • (125,125,50, 100, 100) = (location on ‘x’ L->R, location on ‘y’ Top->Down, size in pixels, Height)
  • ‘Fill’ applies to anything you create after
  • Things occur chronologically
  • ‘++’ means add 1
  • ‘+=’ means add the 1st and 2nd variable and make it equal to the 2nd variable

After break…

 

VECTORS:

  • Speed – Scalar Quantity
  • Velocity (has a direction) – Vector Quantity
  • Position,  x and y, can be represented as a vector
  • Velocity Vector = Final Position – Start Position
  • Start Position + Velocity Vector = Final Position
  • ‘.add’ is vector addition
  • F=ma – Force = Mass x Acceleration

NOTES:

  • Interesting how you can change the colours randomly (FOLDER: Day 1, Test 2, Workshop 1 and 1.1) – could be a cool effect to see on an object in AR
  • Final flocking example (Workshop 2) could be really interesting see in VR or AR… Is there a way to apply this (easily) to objects in Unity? Could be worth finding out…
