Pra vídeo editing o peso dos componentes são

  • Tier 1: Processador e Ram
  • Tier 2: Videocard.

Pra um PC gamer, o peso dos componentes é inverso, então é só comprar a placa de vídeo mais cara e o processador com custo benefício pra focar mais em james


Melhor opção mas aperta o budget

Basic trigonometry for game development


two distinct points (for example, a game object position and the mouse cursor position) in an area can always be two corners of a Right Triangle (Triângulo-retângulo in ptbr). A triangle has three sides: The Hypotenuse, the Adjacent and the Opposite.

The distance between two points in the X axis corresponds to the Adjacent side of a triangle, The distance between two points in the Y axis corresponds to the Opposite side of a triangle.

The Hypotenuse is the shortest distance between the two points.

This means we can use trigonometry to handle many interactions between objects when programming visual stuff.
