Bug Report: ShapeCast2D Detection Issue

[ismettaha]

Describe the bug

ShapeCast2D is not functioning as expected with CircleShape2D. It shows unpredictable detection behavior during collisions.

To Reproduce

Slowly move the 'target position' parameter of the ShapeCast2D, with CircleShape2D, towards a CollisionShape2D beneath it, run force_shapecast_update(). This issue is especially noticeable with small collisions and incremental movements.

Expected behavior

ShapeCast2D should reliably trigger whenever it collides with another object. There should not be an large collision intersection area for the detection to occur. This behavior works correctly when using the default engine settings.

Environment:

• OS: Macos Sonoma 14.4.1
• Version: 0.7.26
• Godot Version: v4.2.2.stable.offical [15073afe3]
• Type: Fast Version With Parallel SIMD Solver

Example project(zip)

A project zip file with no add-ons is attached. Please enable 'visible collision shapes' from the debug menu and press space to start the test.

Haven't investigated what causes it, but I was able to reproduce it locally.
