Question by BerggreenDK · Aug 16, 2011 at 08:47 PM · c#rotationfloatsnap

Looking for ideas of how to control specific values from C#

We have two types of objects we add dynamically.

They can be rotated differently.

A) can only rotate 90 degrees, so that gives 4 directions {0,90,180,270}

B) can be rotated in 5 degress, so we have {0,5,10,15,20,25,30 ... 355} (you get the idea I think)

Problem is that we make the user rotate the object and we also need to let the user switch from type A to B and back. When switching back to A, we need to make sure that the rotation matches the rule and if it doesnt, then go for the best/nearest angle.

Does this make any sense to you and you have some ideas, please post them. I am stirring at this and cant come up with a nice solution. Only ugly hacks.

Mathf.Round is your friend

To round to nearest 1, Mathf.Round(value)

To round to nearest 5, Mathf.Round(value/5.0) * 5.0;

To round to nearest 90, Mathf.Round(value/90.0) * 90.0;
