Unity WebGL RuntimeError: integer overflow

2022-08-11 05:02:00 【This is nine】

I found an integer overflow problem today while developing a web version project.

An error occurred running the Unity content on this page. See your browser JavaScript console for more info. The error was:
RuntimeError: integer overflow

A closer look is that there is a problem with WebAssembly instantiation.So I checked the packaged settings.

Let's take a look at WebAssembly in the packaging settingsArithmetic Exceptions

Contains an enumeration of different capture modes for WebAssembly code.

This enumeration is used in the WebGL platform to define the capture types used when performing arithmetic operations in WebAssembly code.

throw	WebAssembly code rounds very large floating-point numbers to int when dividing by zeroThrows an exception in other cases.
ignore	This mode works by limiting floating point values to a reasonable range when performing arithmetic operationsAvoid pitfalls.

Set to Ignore to ignore browser exception errors.

In this way, the error pop-up window will not pop up on the browser side and affect the program running logic.
