Everyone talks about Raycasts and Spherecasts, but rarely do I see people talking about the Overlap APIs. Learn about a powerful tool that I feel is under-represented.
Physics OverlapBox, OverlapSphere, and OverlapCapsule are great tools to use when you are looking to find what's around a point in your scene. This can be helpful when trying to find nearby objects, or if there is enough space to put something down.

I love your vids. Super informative. Thanks for all ♥
i really like how you explain everything, very visual!
Thank you
That was a pretty cool video idea!
Great video!
Another excellent chill video I basically left it running in the background on my first screen while I did my game dev on the other screen.
I'm using cheat engine to show me the XYZ coordinates of the player in my favorite PS2 games so I can plot the points and recreate the levels in my own game (much differently)
Wow I love ur Videos ❤
Love your content bruv. I used to feel like you were too complicated but turns out i was just dumb. Would love to see you recreate mechanics from popular games if thats something youd consider doing.
😅 I'm sure you were not and are not dumb. There are levels to everything. Being earlier on in the journey does not make you dumb. We were all there once!
Thank you. And thank you for the great tutorials.@@LlamAcademy
Hi great video, i followed your HFSM video can help or make video about how make melecombat subsate machine with multiple attack types and enemy animations
Hello from Ukraine, thank you for you work)
Neat video! But is there actually a difference in using, for example, OverlapSphere over SphereCast for detection?
Yes very much so. If you use a spherecast and the origin point is already overlapping something, you will not get that object as a hit.
9:30 I wish you would mention what will happen if your colliders array is for example 10 but in the world game the Physics have found 11 or more colliders
Here is my answer: No error will appear and the game will continue to run limiting the results to the size of the array so if there's 10+ colliders they'll be omitted
That is correct. If you have 50 objects in the overlap radius but your collider is only of size 10, you will still only get 10 because with NonAlloc variants it does not resize your array for you and it will only give you an undefined set of 10 that may or may not be the closest to the origin
thanks for the video i always had some trouble with understanding them, i cant use your sponsor i am already enrolled with the
LlamAcademy :D

How did you debug the sphere cast?
You mean the visualization of the overlaps?
@@LlamAcademy yes
@@LlamAcademy I mean the capsule overlap
I am into your channel. Can you make a video about using git workflow and unity?
Like this one?

I like your videos, but i hate that cringy intro.
I love my cringy intro 😁
learn boy!
