Regression
No
L(a,b) expression in float fields has erratic behaviour when ordering due to using instanceID as an index
Reproduction steps:
1. Open the attached “ExpressionEvaluatorExample.zip” project
2. Open the “ExpressionEvaluator” Scene
3. Open the “Expression Evaluator Example” Window (Test > Expression Evaluator Example)
4. Multi-select all prefab Cubes in the “ExpresionEvaluatorShenanigans” folder
5. Drag the Cubes into the “Root” GameObject in the Hierarchy
6. While the Cubes are selected, In the Inspector Position X value input ‘L(0,9)’
7. In the “Expression Evaluator Example” Window click the first “Output order” button
8. Observe the correct order in the Console
9. Save and reload the Scene
10. In the Hierarchy, select all Cubes again and repeat the 6th step
11. In the “Expression Evaluator Example” Window click the second “Output order” button
12. Observe the Console
Expected result: The “Order you'd expect (by selection)” and “Order you get (by instanceId, which is meaningless)” logs have the same ordering of Cubes
Actual result: The “Order you get (by instanceId, which is meaningless)” log shows the random order of Cubes when ordered by ‘instanceId’
Reproducible with: 2021.3.46f1, 2022.3.54f1, 6000.0.30f1, 6000.1.0a7
Reproducible on: Windows 11
