Rects are used in order to represent simple rectangle. They’re not here to be drawn, but rather to be used in a basic collision system.
For instance, you can get one from Joyau::Drawable#boundingRect.
Creates a new Rect.
/* call-seq: Joyau::Rect.new Joyau::Rect.new(x, y) Joyau::Rect.new(x, y, w, h) Creates a new Rect. */ VALUE wrap<Rect>(int argc, VALUE *argv, VALUE info) { Rect *ptr = new Rect; VALUE x, y, w, h; rb_scan_args(argc, argv, "04", &x, &y, &w, &h); if (!NIL_P(x) && !NIL_P(y)) { ptr->x = FIX2INT(x); ptr->y = FIX2INT(y); if (!NIL_P(w) && !NIL_P(h)) { ptr->w = FIX2INT(w); ptr->h = FIX2INT(h); } } VALUE tdata = Data_Wrap_Struct(info, 0, wrapped_free<Rect>, ptr); return tdata; }
Returns a rect’s height.
/* Returns a rect's height. */ VALUE Rect_getH(VALUE self) { Rect &ref = getRef<Rect>(self); return INT2FIX(ref.h); }
Sets a rect’s height.
/* call-seq: h=(val) Sets a rect's height. */ VALUE Rect_setH(VALUE self, VALUE val) { Rect &ref = getRef<Rect>(self); int _val = FIX2INT(val); ref.h = _val; return val; }
Returns a rect’s width.
/* Returns a rect's width. */ VALUE Rect_getW(VALUE self) { Rect &ref = getRef<Rect>(self); return INT2FIX(ref.w); }
Sets a rect’s width.
/* call-seq: w=(val) Sets a rect's width. */ VALUE Rect_setW(VALUE self, VALUE val) { Rect &ref = getRef<Rect>(self); int _val = FIX2INT(val); ref.w = _val; return val; }
Returns a rect’s abscissa.
/* Returns a rect's abscissa. */ VALUE Rect_getX(VALUE self) { Rect &ref = getRef<Rect>(self); return INT2FIX(ref.x); }
Sets a rect’s abscissa.
/* call-seq: x=(val) Sets a rect's abscissa. */ VALUE Rect_setX(VALUE self, VALUE val) { Rect &ref = getRef<Rect>(self); int _val = FIX2INT(val); ref.x = _val; return val; }
