I know this post is not about the KH Patch but I don't think you're going to read the comments from the patch post.<br />If you need mi email or another way of talking with me (for example, here) you can tell me, no problem.<br />Thanks in advance,<br />Jordi.Jordi Catalan Maderohttps://www.blogger.com/profile/15175307410782043427noreply@blogger.comtag:blogger.com,1999:blog-7303886057277543329.post-59490168806210147032012-05-15T23:23:40.162+02:002012-05-15T23:23:40.162+02:00mmm I didn't get what you need to do.

If (...I did the same thing recently :) it was easy. If (SQRT(|C1X-C2X|^2 + |C1Y-C2Y|^2) <= R1+R2) the collision flag is true. C1 and C2 are the two circles, R1 and R2 is the radius. The problem is the rotated squares D:. If a line y=mx+q limited by two end points A(x1, y1) and B(x2, y2) cut or touch a square/circle, the collision comes, so with a rectangle I need to check four lines. I know also the formula to get the m from the angle, but I don't know the correct formula to check if a line cut a shape...Xeeynamohttps://www.blogger.com/profile/10054561721606704120noreply@blogger.comtag:blogger.com,1999:blog-7303886057277543329.post-35615357636716050552012-04-10T12:24:09.450+02:002012-04-10T12:24:09.450+02:00Regarding to 2 circles collision detection, simply...Regarding to 2 circles collision detection, simply compute the square of the euclidean distance between the two circles centers and compare it with the sum of the 2 radiuses squared (this way you prevent your code to compute the square root).<br />if distance < sum they collide<br />if distance = sum they touch each other in 1 point<br />else there is no collision.Marcohttps://www.blogger.com/profile/00946774956964352190noreply@blogger.comtag:blogger.com,1999:blog-7303886057277543329.post-17857596366629042062012-03-18T10:27:34.316+01:002012-03-18T10:27:34.316+01:00Ho ricevuto la tua richiesta ieri :)Ho ricevuto la tua richiesta ieri :)Xeeynamohttps://www.blogger.com/profile/10054561721606704120noreply@blogger.comtag:blogger.com,1999:blog-7303886057277543329.post-57256755459750150092012-03-18T10:27:23.645+01:002012-03-18T10:27:23.645+01:00Try to imagine an arm that rotate (http://www.yout...Try to imagine an arm that rotate (http://www.youtube.com/watch?v=dxDgm6GwTFA) or something that oscillates trough a rope.

Non riesco a trovarla da nessuna parte, vorrei discuture con te un pò sull'hacking di Sonic CD 2011 perchè anch'io mi era intrapreso. :) La mia email è tails92@gmail.com.

Also, why would you even need to set the collisions for an object that is not centered? If so you just need to specify the area where the sprite is before-hand.Truthkeyhttps://www.blogger.com/profile/04820118390652377131noreply@blogger.com
