Im thinking of a better mouse wheel sensitivity solution

Questions

ok , no playground needed for this question ,

I was just helping another user with a PG and set up an ArkRotateCamera. As always , i find the default mouse wheel sensitivity way too strong.

In general this is always the case for so many generic playgrounds setting up primitives with default sizes. I set my camera radius to 10 and if I roll the mouse wheel a single click it practically does the entire distance.

Anyway , While it could be better to change the default , that is not a silver bullet because obviously , for larger scenes and objects it would be too weak.

So I have actually solved a similar issue before with camera’s in my unity projects many years ago.

I created a dynamic sensitivity , a ratio based on the current radius. Im sure I dont have to explain the logic , it worked very well.

I do understand that even that is not a silver bullet because it wont cover evey use case. So this is what im thinking :

everything you have remains the same , so nothing gets broken and users can still set it manually as they please or write their own solutions.

but we can add a wheel sensitivity mode to the camera. Then we would have two modes ,

DEFAULT and DYNAMIC

it defaults to the DEFAULT mode. So as said above in this mode , eveything functions as normal.

If you set the mode to DYNAMIC , then it uses the calculated ratio. This would require one extra property ,something to say what that ratio is.

I have been around in the forums for a long time and have never contributed to the Engine ever , So i think this time around im going to try do it myself instead of expecting somone else to do it.

I didnt want to post in feature requests because im not sure if its something wanted , or even how difficult it will be to do… let me first get it working in a loca repo and then I will get back to you all.

This is how the similar function is done in the Sandbox -

Did you try?
camera.wheelDeltaPercentage = 0.01

May be I missing the point a little, but what do you think about building a neural network where you calculate the speed of the zoom in relation to the acceleration of the wheel? :crazy_face:

Yes, I faced the same issue eventually. There’s one part though that comes from the ‘initial’ mouse wheel sensitivity. The one you set on the system. I find it very hard to counter (can we even capture and record it, I have no faen clue). The only real solution I found so far is to set a ‘reasonable’ default and next implement user settings to act on sensitivity/delta.

Well, I guess you got my point :grin: I would upvote it :+1:… if by any means possible :thinking:

You lost me there :dizzy_face: Too many complex words for me to handle :joy: :sweat_smile:

actually in all my apps i do this , funny just looking at its behaviour and reevaluating this all without looking at any code , it seems this is calculating a dynamic amount.

SO I guess this doesnt need any more work from me , what it needs is just using this value by default , unless someone thinks there is or knows about a reason for this to not be the default? maybe im missing something but the 0.01 is totally usable , the current default , which i think is zero , is not…

So as I :slight_smile:

I am wondering too :see_no_evil:

Oh, really? Just had a quick look back at mine and guess what… so, do I :grin:
But then again, for me, it’s just a ‘reasonable’/compromise value. If you set your system to use a 3-rows wheel sensitivity, it’s kind of not the same feeling than with the default.

yes, no default is ever going to be perfect , but im sure we can now at least all conclude that 0.01 is a better default than the current default of zero.
