Good morning, I am very beginners student of openFrameworks. I'm following a tutorial trying to create a new class with openFrameworks but I cannot compile it in the right way. This because the tutorial I found in on Visual Studio and i'm working on a Mac with Xcode. This problem is blocking me and I cannot go on with the course. Can someone help me translate the code to create a new class from Visual Studio to Xcode? The language is the same, but the programme in this case is slightly different. On Visual Studio the files are Class.H and Class.Cpp THIS IS CLASS.H VISUAL STUDIO #pragma once #include ofMain.h class ball { public: ball(); void setup (ofVec2f initialPos, ofVec2f initialVel, float rad); void update (); void draw(); ofVec2f pos; ofVec2f vel; ofVec2f radius; }; CLASS.CPP VISUAL STUDIO #include ball.h ball :: ball();{ } void ball :: setup(ofVec2f initialPos, ofVec2f initialVel, float rad); { ofVec2f initialPos;
