Idk how to do it concretely but in theory, get the touch coordinates and convert that to world space

bronze solar Mar 28, 2022, 2:40 PM

#

I think the most confusing part about this is, that a friend who helped with the script originally decided to use physics.raycast for another script that kinda does what I need

        for (var i = 0; i < Input.touchCount; ++i) {
             if (Input.GetTouch(i).phase == TouchPhase.Began) {
                 
                 // Construct a ray from the current touch coordinates
                 Ray ray = Camera.main.ScreenPointToRay(Input.GetTouch(i).position);
                 // Create a particle if hit
                 if (Physics.Raycast(ray))
                     Instantiate(particle, transform.position, transform.rotation);                
             }
         }

This might be of help

The important thing is that when user taps on the screen, you want to run that raycast through the camera's view point. You must make sure you direct that ray as per the view frustrum of the camera, otherwise you'd just shoot it directly forward as if you're in orthographic mode.

#

In perspective camera mode (I'm assuming this is what you're using), your camera will angle out the further to the edge you are, so you must make sure to account for it

Understood

#

I think I messed up by letting a friend help me for this project

#

Kinda being thrown into a script that already has a bunch of connections/references that makes it so I can't just replace parts without destroying entire sections

#

And I'm not at a level where I understand what is being referenced too/what its function is completely

#

I'll look into everything you said though, appreciate the help

Using existing code is tougher, true. But it can teach you a lot more why we code the way we do

bronze solar Mar 28, 2022, 2:46 PM

#

I think its also having different names for the same thing per script

stiff sluice Mar 28, 2022, 2:46 PM

#

I wouldn't worry too much if I were you, just start a new project and toss and turn with whatever piece of logic you want to test out, when you're done bring in that code into your project

#

Yeah if you started out with poor code it's going to be a bigger headache lol. If you're not comfortable with coding yet it's best to start with a blank project and test things out that way

bronze solar Mar 28, 2022, 2:46 PM

#

Definitely true, kinda time sensitive though which makes it a pain

stiff sluice Mar 28, 2022, 2:46 PM

#

Then you can attempt some refactoring with your friend's project. Ask them to guide you if you get lost.

#

Yeah, at work we do the isolated project to get it figured out quick. If it works in isolation but doesn't in integration then we've got some ghosts in the code that we need to exorcise 😆

#

Good luck, I'll toss some lines in mine and then bounce for the day.

bronze solar Mar 28, 2022, 2:48 PM

#

Hahahaha

#

Good luck to you too, thanks for the help.

#

Definitely gonna do a deep dive into unity programming after this project and just be able to take my time/explore

#

Love the idea that you can create pretty much anything once you know how to/understand the tools given

#

Enjoy your day!

Absolutely, same to you. And I'm a beginner at Unity too
