[help] Drawing a polygon on cSurface

Hi,

I tried looking at the function signature but found that it only accepts ONE lppoint as arguments... even though you are to specify how many points are contained!

Small example on this, maybe?

LPPOINT pts actually takes a pointer to a list (array) of points. The LP part stands for long pointer (I think.)

Code

// Simple triangle example


// Define a list of 3 points
POINT tri[3];
tri[0].x = 16; tri[0].y = 0;  // First point
tri[1].x = 0;  tri[1].y = 32; // Second point
tri[2].x = 32; tri[2].y = 32; // Third point


// Draw the triangle onto a surface
mySurface.Polygon( tri, 3, 1, RGB(255,0,0) );
