Optimization notes

Operations that trigger a new draw call

Whenever these operations are alternated, a new draw call is triggered. To get around this, drawing operations should be grouped together by their operation type.

Operation types are:

  • love.graphics.draw with love.graphics.newImage
  • love.graphics.draw with love.graphics.newText
  • primitive shapes including: love.graphics.line, love.graphics.rectangle, love.graphics.circle, etc...
  • love.graphics.print
  • love.graphics.draw with love.graphics.newMesh

Batch text drawing by using a single newText object

Love's Text object allows you to add additional colored text nodes to it. This means we can add multiple strings to the object and then do a single love.graphics.draw(MyTextObject) call.
