##### Mathf actions?
« on: August 07, 2012, 09:13:58 AM »
If possible

I'm trying to to do this:

But can't figure out a way to do it with the current actions.

Seems like there are some useful functions in this list:

http://docs.unity3d.com/Documentation/ScriptReference/Mathf.html

I found an 'Float Round' action which has been very useful so far.

Thanks

Hi,

not sure what you mean by "I found a float round action", I could not find one in the forum nor the official actions

Sorry, got it wrong way around.

http://hutonggames.com/playmakerforum/index.php?topic=2073.0

Just saying that that one was useful and it's just a small part of the mathf functions.

But, what I'm after specifically is an action that rounds a float to the nearest 0.5 (or any input value).

So, if float = 1.2 then it rounds to 1.0, if 2.8 then it rounds to 3.0, etc.

I think it's called Mathf.Floor?

Hi,

This is exactly what round is doing, so the action I created will work for your case.

1.9 would be 1 if you used floor. 1.1 would be 2 if you used ceil

Ah, I was using a different action. I've just downloaded your action but I can't see how to convert a float (say 1.65) to the closest 0.5 (would be 1.5).

Also, I can't see any option for floor or ceil.

Sorry if I'm missing something.

Thanks

Hi,

There is not such math function to round to 1.5 rounding always returns an int. to achieve this, multiply by 2 your value, round them, and then divide by two,

1.65*2 = 3.3
round(3.3) = 3
3/2 = 1.5

1.8*2 = 3.6
round(3.6) = 4
4/2 = 2

As for floor and ceiling. I'll see if I can do them in the next few days.

bye,

Jean

Why didn't I think about that. :s

Adds a few extra steps but that's fine for now.

Thanks
