Bug all Physics2d.Boxcast variants are broken

Physics2D.BoxCast
Physics2D.BoxCastAll
Physics2D.BoxCastNonAlloc

these are all broken, that never takes distance parameter into account.

Consider the following code

Code (CSharp):

1. var size = new Vector2(1,1)
2. var angle = 0f;
3. var distance = 5f;
4. Physics2D.BoxCastAll(origin, size, angle, Vector2.down, distance, layers);

this code will fail to detect anything within the 5 distance, and will only detect something touching that 1 x 1 size

in contrary to this code

Code (CSharp):

1. var size = new Vector2(1,1)
2. var angle = 0f;
3. var distance = 5f;
4. Physics2D.CapsuleCastAll(origin, size, CapsuleDirection2D.Vertical, angle, Vector2.down, distance, layers);

the capsule cast version works properly and correctly detects everything in 5 distance away

 

To anyone having the same problem
and to the unity team

I found that if you change the

Default contact offset

setting in Project Settings/physics2d
from

0.001

(the default value) to

0.01

, it then starts to work properly

Please take a look into this

 

As with all bugs, please file a bug report with a repo project if you can.

 

I have run into the same issue and I have found that the bug is dependent on what the scene starts with the default contact offset is.
What I have found is

• if you start the scene with an offset above 0.0024 the bug will not occur
• if you start the scene with an offset of between 0.0024 & 0.00125 the bug does not occur until the offset is below 0.00125 and will stop when you set it back to above 0.00125. Weirdly enough though if you start on 0.00125 then lower it down to 0.00124 or 0.00123 then change it back to 0.00125 then the bug remains until changed above 0.00125
• if you start the scene with an offset below 0.00125 then the bug occurs until the offset is above 0.0024

I tested this by changing the value through the editor and pausing while changing it. I will start to make a bug report tonight but I may be interrupted before completing it.
