HGE:Tutorials:Rectangle Class
From GPWiki
[edit] hgeRect classhgeRect is an HGE helper class for implementing rectangles. It is useful for collision detection. hgeRect has 4 member variables: x1, y1, x2, y2
[edit] Constructor:hgeRect(float x1, float y1, float x2, float y2); [edit] Member functions:TestPoint(float x, float y): Returns true if the specified point (x, y) is in the rectangle. Intersect(hgeRect *r): Returns true if the specified rectangle (r) intersects the rectangle. [edit] Creating an hgeRectCreate an hgeRect instance in one of the following ways. They are all performing the same operation: setting the myRect's coordinates to (0, 0, 64, 64). 1. Use the constructor hgeRect myRect; myRect = hgeRect(0, 0, 64, 64); 2. Single statement hgeRect myRect(0, 0, 64, 64); 3. Individually populating the member variables hgeRect myRect; myRect.x1=0; myRect.y1=0; myRect.x2=64; myRect.y2=64; Next section: Simple 2D Game |
