AssetDatabase.CanOpenAssetInEditor

Parameters

Returns

bool True if AssetDatabase.OpenAsset can open the asset. Otherwise, false.

Description

Checks whether the Unity Editor can open the asset with the specified EntityId.

Use this method to check whether calling AssetDatabase.OpenAsset would open the asset. The asset must be saved to disk. Otherwise, the method always returns false.
