How to clean up list entries when objects are destroyed in Unity?
The best way that I came up with is, according to the observer pattern, to notify all classes where the object was stored about its destruction and remove references to it from there.
That's what I ...

Best way to implement a carrying tray in VR using Unity
I have found a suitable solution using both Unity's built-in materials and a script that uses a trigger as a parent modifier.
Both the tray's and mug's collider has a material attached that raises ...

Best way to implement a carrying tray in VR using Unity
It sounds like you've already figured out the solution:
I'm thinking of some kind of magnet-like system where if you drop an item onto the tray, it becomes stuck until you manually take it off.

Simulate Velocity For A Projectile Moving Along A Spline
I think when a projectile is thrown it should have a burst of speed at the start and begin to rise slower as it reaches its peak height. Then as it starts to fall it should gradually begin to fall ...

Simulate Velocity For A Projectile Moving Along A Spline
Remove the spline and split speed into 2 components X,Y ie Vector2.
Fix a horizontal velocity.X from the spline.
Apply a negative rather large value to velocity.Y, and each step adjusted for delta ...

Getting a pixel of Sprite at the cursor position in Unity
This is a super old question, but I was struggling with this for a while, used the code from Savlon's answer and then found it wouldn't work if I moved or scaled the object at all. After hours of ...

You can first check whether "any" key has been pressed, then check if the key you're listening to has not, to respond only to presses that were not that key.

Game loop isn't performing well enough, so my frame rate is too low (Windows Form + GDI+)
I wonder, do you really need to render noise that is uniquely random down to the pixel?
Or would it be okay if it just appears random?
If you're alright with an approach that relies on staggered ...

What would be the best way to gradually increase the speed of a 2D arcade game with gravity physics in Unity?
this might not be consistent for different framerates - is that right?
Time.timeScale is independent of framerate. Unity will continue to try to render at the same ...

Flying AI shakes when chasing and avoiding obstacles simultaneously
If I'm understanding correctly, the issue is that you're oscillating back and forth between two states...
State 1 is when you're out of collision range and it moves normally.
State 2 is when it's ...

Euler Angle X is wrong after using Quaternion.LookRotation
If you want to enforce angular limits, keep it in terms of angles from the start. Don't count on an automatic conversion from quaternions to Euler angles to give you angles in a specific range, ...

Fast way to calculate angular intervals and occlusion of circular objects in a 2D vision cone
Here are some optimization suggestions:
1. Filter unnecessary tests
Objects located outside the field of view circle(distance>r1+r2) do not need to be detected. ...

Fast way to calculate angular intervals and occlusion of circular objects in a 2D vision cone
My first move would be to use a Raycast at regular intervals between the start & end angles. In other words:
