BuildPipeline.GetCRCForAssetBundle

Parameters

Returns

bool True if the method successfully reads the manifest file and extracts the CRC value. False if it cannot find the .manifest file associated to the targetPath or fails to parse the CRC value, which might happen due to incorrect paths.

Description

Extract the CRC checksum for the given AssetBundle.

A 32-bit checksum is generated during the AssetBundle build process and recorded in the .manifest file and exposed by this method.
