Title: Getting a second co-ordinate
Post by: mike_g on March 12, 2007

Its kind of embarrasing asking such a simple maths question but:

Say I have a start x/y co-ordinate, an angle in degrees, and a distance. How can I get the end x/y co-ordinates from this?

If I remember correctly, you can do it something like this:

Code: [Select]

endXpos = startXpos + sin( angle ) * distance
endYpos = startYpos + cos( angle ) * distance
