Title: Transformations not being applied to the points of the vectors
Post by: nick1702 on December 04, 2021, 09:51:31 pm

Hi, I am trying to code a Hilbert Curve using SFML and am running into problems involving transformations. My thought was that if I made an object transformable, and made that object have a vector of vertexes inside of it, I could transform that object and the vector would be transformed however I am seeing that the transformations are applied to the object, but not the vector inside the object, so when I go to draw my vector the transformations are not applied. I must be missing something on how this works. How could I go about actually transforming the points within the vector easily so that they show up on the display? Thanks.

You most likely want to use getTransform() (inherited from sf::Transformable) with your RenderStates used to draw the array:
