Drag & Drop

[left stone]

Smart

[granite wyvern]

after you click and it disappears, can you double click on it in the hierarchy and see what its values for its position are

[brazen galleon]

When in game

[granite wyvern]

i think the issue is with it being in world space

the tutorial you're following is supposed to be for a normal canvas

[brazen galleon]

@last haven what's ClickManager? Is it the canvas?

[last haven]

oh

yes its the canvas

[brazen galleon]

take a screenshot of it

[granite wyvern]

try with camera space or overlay

[last haven]

i guess i make a new canvas for that

cause the click manager worked pretty good set up like that

no harm right?

[granite wyvern]

yes just right click -> UI -> Canvas

don't set it to world space and put the same script and give it the same children

this is the set up of the canvas for the tutorial

the one you're following

[flint terrace]

Really most of this stuff should be using the built-in interfaces for Events, IDragHandler would be appropriate, and hell, there's even some suspiciously okay looking example code
https://docs.unity3d.com/Packages/com.unity.ugui@1.0/api/UnityEngine.EventSystems.IDragHandler.html
Though, if you're following a tutorial it might be best to stick to how they're getting it done.
It seems odd the way you're moving things to and from canvases?

[last haven]

it uses idraghandler

https://pastebin.com/FgQZc07r

but now on that canvas it doesnt do anything at all

[flint terrace]

What's the object you're clicking on look like?

[flint terrace]

What's Task Button?

[last haven]

yea that the sprite i just realized was unnecessary

now it looks like this BUT when i remove the sprite

[flint terrace]

Does it work now it's set up like this?

[last haven]

ah now its a sorting problem

wait

[flint terrace]

That width and height seems really really small but I'm unsure whether that'd affect anything

[last haven]

they are invisible when not in pause but they do show up and in the right spot

[brazen galleon]

probably wrong position or sorting order.

[last haven]

yea its sorting order im now looking up how to change that. I only know how to do it with sprites there is just a "sorting order" option

[flint terrace]

the canvas has a setting

[last haven]

ah jesus

[brazen galleon]

select one of them and check the position

[flint terrace]

Your camera may be hiding the UI layer?

[last haven]

oh look at the video when i pause the game and it changes from the game screen to the scene view they do show and they show in the correct position

[flint terrace]

What are their Z positions

[last haven]

i tested with 0 and -1

[brazen galleon]

actually select and take a screenshot.

[last haven]

the camera is -10

[last haven]

k

[flint terrace]

They should all have z as 0

[flint terrace]

Can you check your camera isn't excluding the UI layer from rendering

Also, that's world space, not UI space

so that actually seems wrong

[last haven]

i tried with different layer

[brazen galleon]

Also this:

[flint terrace]

if the canvas is ScreenSpace Overlay and you're drawing stuff at ~(-400, -250) That is not going to be on the screen

[brazen galleon]

I imagine 1-1.5 pixels won't show very well

[last haven]

it is not pixels but units

[brazen galleon]

Well, I'm sorry to tell you, but it is in pixels.

At least if you are using screen space canvas

[last haven]

wtf

[brazen galleon]

I think I'm gonna stop here. Because it feels like it's going no where. Do your learning of the ui system, follow the tutorial exactly as it is and make sure it works. Only then attempt making changes.

[last haven]

I am not trying to make changes

[brazen galleon]

Yeah. You're trying to use some steps from the tutorial in a different context. That's even worse. At least if you're not understanding what you're doing.

[last haven]

I mean u are saying its pixels and i am sure u know what you are talking about but it did show up properly before with width 2 and height 1

i could see it and click t

it

the drag&drop behaved weirdly but it was not 2x1 pixels

and now you are acting like I am crazy to expect to see a 2x1 pixel image when it showed up perfect before

and no alternative

[brazen galleon]

Probably when the canvas was in world space right?

[last haven]

i can make it bigger i tried

it did not show it just was huge

yes

it is huge in the scene but does not show in game either

[brazen galleon]

Well, then reread my message again. I said it's in pixels with what canvas?

[brazen galleon]

Did you also fix the negative position?

[last haven]

placed it directly in the scene

oh

[last haven]

ok

now wiht 0 0 0
and 200x100 it shows

alright

still got issues but this is the first progress in 4 hours 😅
oh btw thanks alot for all of your time I am very grateful

ok drag&drop works which is nice but it always spawns at the bottom left
never out of screen or somewhere else

always the pivot at the outermost bottom left corner

[brazen galleon]

As you were told before, you'll need to spawn in in screen space position, not world space.

[last haven]

GameObject result = Instantiate(mathTask, rbody.position, Quaternion.identity);
so in here instead of the value of the rigidbody position is my guess

[last haven]

is that was screen space is? they always stay at the same screen position?

@flint terrace is that what the screen space camera is?

[flint terrace]

Screen space is that the positions are in screen coordinates

[last haven]

you see in the video the mathTasks stays put on the screen

[flint terrace]

Yes

[last haven]

that is inherently its behavior when the canvas is in screen space?

[flint terrace]

If you don't move something in screen coordinates, yes, it stays still on the screen

[last haven]

damnit

of course I dont want that

so all this trying to get "screen space" to work

was just a waste

I want it to be in the world

damn

[brazen galleon]

You can still make it stay in the same world position if you move it in script.🤷‍♂️

[last haven]

I don't even have close to an idea how to do that

it feels like that object shouldnt be on a screen space canvas

[brazen galleon]

Not that hard if you learn properly.

[brazen galleon]

But I can agree with that.

It should've been a sprite renderer + collider in the first place. I've no clue why you decided to get involved with canvases

[last haven]

because of the textMeshPro element it needs a canvas

[brazen galleon]

There's a world space TMP component afaik

Might be mistaken...🤔

[last haven]

so my initial attempt wasn't even off using a sprite with a small world canvas for the textmeshpro I just need a different drag&drop solution?

[brazen galleon]

Yes. In case I'm wrong, you might still need a canvas for tmp and will need to sync it's position with the sprite in world space.

[flint terrace]

The generic Text Mesh Pro text doesn't need a canvas and is just a mesh in world-space

[brazen galleon]

Ah, so there is one

[flint terrace]

If you're looking to switch this to world space you'd want to look for examples with 2D physics that have drag and drop behaviours

I'm sure Melv has one

[flint terrace]

Somewhere in these examples https://github.com/Unity-Technologies/PhysicsExamples2D, I believe many of them use a drag and drop script
