Rotate the sprite the same as the angle your using. So if it is at the top of the circle use 90 degrees, if it is half way between the equator and the north pole then 45 degrees etc...

Now I know how I can get x,y-position of each sprite using the cosinus and sinus functions together with the radius and angle. Only the problem I am currently experiencing is the putting the sprites nicely on the line of the circle. It's some rotation related thing but I don't get it. The basic idea is to have an earth and then all kind of items such as buildings to be positioned on the line/circumference of the circle and then follow the form of the circle. I only don't get it. I know I can get the x,y position for these (building) sprites the following way: var radius: Number = 50; var angle: Number = 60; var x: Number = Math.sin(Math.PI/180 * angle) * radius; var y: Number = Math.cos(Math.PI/180 * angle) * radius; Now I only have the problem to nicely rotate the sprite in such manner is basically following the form of the circle. I have made a drawing of how the sprites and/or buildings (every rectangle is a sprite) should be placed on the circle [1] but I don't know how i get that nice rotation calculated. Anyone having any idea how to do this? Too bad, they didn't discuss this during math class :( [1] http://i35.tinypic.com/2a7daop.jpg Weyert _______________________________________________ Flashcoders mailing list [email protected] http://chattyfig.figleaf.com/mailman/listinfo/flashcoders __________ Information from ESET NOD32 Antivirus, version of virus signature database 4588 (20091109) __________ The message was checked by ESET NOD32 Antivirus. http://www.eset.com __________ Information from ESET NOD32 Antivirus, version of virus signature database 4588 (20091109) __________ The message was checked by ESET NOD32 Antivirus. http://www.eset.com _______________________________________________ Flashcoders mailing list [email protected] http://chattyfig.figleaf.com/mailman/listinfo/flashcoders
