Sprite Not Clickable

[deep dagger]

Okay so you have a sprite, and it's box collider isn't acknowledging clicks

except halfway down

[brisk walrus]

wait a minute

[deep dagger]

?

k

[brisk walrus]

I think Ik the issue

[deep dagger]

ahh excellent

[brisk walrus]

how do I layer colliders?

[deep dagger]

You can't

one collider to rule them all

[brisk walrus]

(i have another collider right where that one is)

thats why its not working

[deep dagger]

yeah that'll do it

okay you have to pick ONE

whomever is "lower" on the hierarchy, their collider is "in front"

[brisk walrus]

but, what this collider is for is a button. The otherone is for a wall

[brisk walrus]

oh ill do that then

[deep dagger]

Funny I was just dealing with this today

[brisk walrus]

so how would I put the button one in front?

just put it at the bottom of hierarchy?

no that doesn't work

changing the z layer also doesn't work

[deep dagger]

well some good news Buttons ARE UI, and UI is programmed to always be on top of SPrites

And for that reason, I would say don't mix a button and UI

UI should be reserved for game menus and such - the things you absolutely WANT on top of your game world, and things you expect the game world to never block or interfer with

Instead, what you want is a clickable sprite

[brisk walrus]

yeah put ui always follows the camera

thats why I didn't use it in the first place

[deep dagger]

Okay - Correct me if I'm wrong, but you said you have a Button component on one of your items right?

[brisk walrus]

OnMouseDown

Thats what I have

With the collider

[deep dagger]

There is no Component named "OnMouseDown" that I am aware of. OnMouseDown is a function.

[brisk walrus]

Yeah

I have a script with OnMouseDown on that “button”

[deep dagger]

Okay the object with that, can you highlight it in your hierarchy and send me a screenshot of the inspector

[brisk walrus]

https://www.youtube.com/watch?v=-0eqAUkKQpI btw this is how I setup the collider thing

except i made it a trigger

[deep dagger]

Okay what I was looking for, was to make sure you didn't have the Unity Button Component on it. that's all

you have a custom class named Stage Button

[brisk walrus]

yes

[deep dagger]

and the stage button is lower in the hierarchy than the wall?

[brisk walrus]

idk how to check that

i mean the wall is in the parent "StageAnimatronics"

[deep dagger]

You just checked it 🙂

in the world of Unity, anything at the bottom of the heirarchy is "on top" of the other things

[deep dagger]

How'com your stage button isn't in the Canvas?

[brisk walrus]

ohhhh

[brisk walrus]

cause when you said bottom I thought you wanted me to put it on the literal bottom lmao

also its not ui

[brisk walrus]

still isn't working 😕

[deep dagger]

All your 2D things SHOULD be under your canvas

[brisk walrus]

but canvas's are for ui I thought?

[deep dagger]

Canvas = all that is 2D

[brisk walrus]

well what would that change anything?

[deep dagger]

It might

standby family wants to talk to me

[brisk walrus]

I though canvas was ui only lol

[brisk walrus]

aight

[brisk walrus]

it just fucks everything up

camera can't find the player

shit breaking down

[deep dagger]

Hold-up. Your camera can't find the player when you put it in 2D?

[brisk walrus]

when I put everything in the canvas

[deep dagger]

okay that's weird too

hey I don't think i can devote proper attention to this I keep getting called by my family and it's making it hard to focus on unraveling problems sorry

[brisk walrus]

oh your good man

rn im working on the models, and its not like its that important till I get in later on in developing.

Im sure its an easy fix though

[deep dagger]

It probably is

[brisk walrus]

like most things usually lol

[deep dagger]

okay I THINK I'm back

how are you faring?

[brisk walrus]

Haven't been able to figure it out

been modeling really though

[deep dagger]

ahh okay

well then I'll close the thread. Let me know if you still want help- when you want help

[brisk walrus]

well right now

just finished a model rn lol

Ive tried to make the z axis larger, put it higher on the hierarchy, what else can I try

I mean is there a way besides using colliders to be able to click on something?

would something like this be a solution?

[deep dagger]

It can be multifaceted

For example, you might be using OnCollsion when really, you need OnCollision2d

so that's an area that can go amiss

[brisk walrus]

Honestly is there just an easier way to make a button?

[brisk walrus]

Im using the OnMouseDown

[deep dagger]

Well one way to debug is to isolate the item

[brisk walrus]

wdym

[deep dagger]

make the button a prefab.

Then make a new scene, purely for testing purposes, and put the button in there and see if it works

if it doesn't even work right in a fresh scene, you've somehow hooked it up wrong

[brisk walrus]

yeah works perfectly fine

[deep dagger]

Okay then the good news is that you hooked it fine

the bad news is you have some kind of z-fighting error.

Now you're saying you've got this button on top of a wall, and the wall also has a colider?

[brisk walrus]

yes, to prevent the user from just walking through the walls out of the building

[deep dagger]

Are the wall colliders set to Kinematic?

[brisk walrus]

they don't use a rigid body

just a collider

[deep dagger]

okay just collider. hmm

okay try putting your wall switch to Layer 5 - UI - for science?

[brisk walrus]

the button? or the wall itself

well it doesn't matter cause it doesn't work both ways

[deep dagger]

I was gonna say the button itself

[brisk walrus]

i tried both

neither worked

[deep dagger]

huh

okay give me un momento. I'll try making something similar and see if I can pull it off.

What version of Unity?

[deep dagger]

okay cool I'm on that version as well

standby I gotta do a build.

[brisk walrus]

K

[deep dagger]

okay I did a really silly quick scene setup, with a "fake wall" as a 2D Sprite, and a fake button that says "test me" so that is working

and I just added a random circle, and script with an OnMouseDown and it's working

and the circle is on top of the "Wall"

But I have everything organized under the Canvas, and the Canvas is set to "Screen Space Overlay"

[brisk walrus]

Hm ill have to look into that later

[deep dagger]

sure thing.

If I recall correctly, there are a lot of 2D functions that don't work correctly once they are outside of the 2D Canvas.

If you take a full 2D tutorial course, the first thing that's usually done is they teach you how to setup your camera to work with your canvas properly. There are various "modes" a canvas can operate in.

"Screen Space -Camera" means the 2D elements stick to the camera and never move.

In Screen-Space - Overlay" , anything marked a UI sticks to the camera (buttons, UI text, etc,), but sprites do not, and it can be very useful for a top-down game like yours.

[deep dagger]

yeah if canvas aren't setup from teh get go they can get a lil funky. I just broke my 2D game mucking around with it 😛 But I'll get it fixed up

[brisk walrus]

so do I have to completely redo everything?

[deep dagger]

Maybe? But maybe not. Try dragging your button and wall into your 2D Canvas first. and then if you notice it works FINE when under the canvas, but not when it's outside - then yeah you have to do something to make it work UNDER the canvas

[deep dagger]

make sure you are in your game view with you click the button

[brisk walrus]

did you watch the video?

the button just goes out of the map

[deep dagger]

Yeah but you're just trying to test one thing.

So for this unique case, press play. Drop the switch to the Canvas. Then in scene view, physically move the button to the right space. Then in gameview, try clicking it

if it sudedenly works fine when under the canvas, then you have new knowledge.

[brisk walrus]

k

yeah I moved it and it still doesn't work

[deep dagger]

but it works fine by itself in a scene where nothing else exists?

[brisk walrus]

well yes, because there is no collider layering on top of it

[deep dagger]

the weird thing is that I was able to put a simple item on top of another collider, and it worked fine

[brisk walrus]

huh

this is quite odd

[deep dagger]

only other thing I can think of is Pos Z needs to be changed

[brisk walrus]

I tried that as well

[deep dagger]

well crap I'm sorry I don't know why yours is broke

and I don't know how to help

[brisk walrus]

:(

[deep dagger]

You can try setting up a new version of the scene from scratch to see if that fixes it

it's annoying but I've solved problems that way
