Hey, I'm using your classic Sonic spritesheet in a fan game and I wanted to check with you to see if it'd be okay for me to use your classic Tails sprites to go along with him? Tried to PM you, but your box might be full?

Aye! Sorry, couldn't find rules listed anywhere.. and when I did a forum search this seemed to word what I was looking for so accurately!

Was just about to make a topic asking this very same question....

Thanks that I will be helpful for switching movement modes! Still need to figure out if I'm calculating angle correctly as a speed modifier though.. To go into more detail, I pretty much have a one pixel sensor that I'm using to scan a set of 16x16 tiles.. it records the height value for each pixel of a tile and calculates the angle using Atan2.. Sometimes Atan2 return a negative angle value, I'm not sure if it's okay that I leave it at that value? I feel awkward asking, but I think my physics are a bit broken, might take a while for me to figure it out on my own.. ( Nice to know C works that way! I've never ventured far from Blitzmax or Monkey.. )

Thanks for the replies.. currently attempting to write a program that should calculate the heights and angles of the tiles for me.. So if I do the calculations as you suggest and still obtain a negative angle, would it be okay just to add that negative angle value to 180? Trying to find the best way to make this process as automated as possible! eh.. All the programming language I'm familiar with use the downward Y axis as the positive value.. This part still goes a bit over my head! Is there still just a single angle value per tile when calculating the speed?

Thanks so much for the explanation!! Mind verifying that I'm calculating the angle correctly? Still unsure! (I enlarged the image, the markings on the sides of the tile were originally one pixel each, the tilesize is 16x16) Also, what's the significance of converting the angle to radians? Does the ATan2 equation eliminate the need for that?

Hey! I'm finding myself a bit stuck here.. Would appreciate any advice! So from what I understand, in Sonic games each 16x16 block of tile is assigned a single angle, right? For someone who isn't very knowledgeable of mathematics beyond basic algebra; What's the easiest way to determine the angle that a tile should give off? If it's impossible to do without learning more advanced math, what would I need to learn?
