how to scan object that player looking at

[ebon wraith]

i need make own custom function that will get objects by their colliders

[quick saffron]

Okay. What's the problem?

[ebon wraith]

i mean udon already has function for that

but

it requires me put script on every object that i want to be detected

so like 10k objects

and i want instead hold it in just one controller script

that will scan object by collider

object that player looks at

[quick saffron]

Look at? So you want to get a reference of the object that the player is looking at?

[ebon wraith]

or more exactly pointing at

because in vr its from hands

not head

[quick saffron]

Well, that's pretty simple: just cast a ray from the camera and the hit would contain a reference to the collider/GameObject.

Or from the hands

From whatever you want to point at things.

[ebon wraith]

some exampleee?

[quick saffron]

Google it. There are plenty of examples of raycasting.

[ebon wraith]

yeah but i mean theres pretty much of excessive code

[quick saffron]

Well, that's something you've gotta learn to deal with. Only use the parts that are useful for you.

The docs page would usually only have relevant examples, so look at the docs as well.

how i stop raycast after hitting first thing

[quick saffron]

Umm... A regular raycast only returns one hit(the first thing that it hit), so I'm not sure what you mean by that.

[ebon wraith]

okay i found out

somehow it fires multiple times

also i thought it only stops at colliders

and about mass optimization

would it be better to use very stretched objects or very tiny ones but 2x more of them

[quick saffron]

It fires as many times as you call it.

[quick saffron]

Yes it does.

[quick saffron]

Not sure what you mean by "mass optimization".

[quick saffron]

Nor what that has to do with mass or optimization.

[ebon wraith]

like

every object on map has 2 attached objects with script for teleporting above and and below it

but i could instead stretch it across all size of object and to point out from both sides

and it would be just 1 object with 1 script that would just scan for player position

and based on it teleport either up or down

but no idea if stretched texture would lag more

[quick saffron]

What you mean is that you scale one object up instead of using 2 objects?
Obviously less objects to render means less render calls = better performance. There's no performance impact from scaling objects.

[ebon wraith]

so one big object better than 2 small objects
