If you’re making a game, I think its critical that you implement some sort of entity inspector as soon as possible. Having it makes debugging so much easier since without it you would have to:

• Make code changes
• Save changes
• Run game
• Repeat until you accomplished whatever it is you were trying to do

This process is even worse if you’re using a compiled language, which adds an extra step and wastes even more of your time.

Anyways, here is how I expose properties for my Entity classes in lua.

function Entity:getInspectorProperties()
  local props = InspectorProperties(self)
  -- expose a string variable that you dont want users to be editing
  props:addReadOnlyString('Name', 'name')
  -- expose a vector variable by providing a getter and setter function
  props:addVector2('Position', self.getPosition, self.setPosition)
  -- expose a vector2i variable
  props:addVector2i('Size', self.getSize, self.resize)
  return props
end
