Interactive [Resource] loader.
Interactive [Resource] loader. This object is returned by [ResourceLoader] when performing an interactive load. It allows to load with high granularity, so this is mainly useful for displaying loading bars/percentages.
Returns the loaded resource if the load operation completed successfully, [code]null[/code] otherwise.
Returns the load stage. The total amount of stages can be queried with [method get_stage_count].
Returns the total amount of stages (calls to [method poll]) needed to completely load this resource.
Polls the loading operation, i.e. loads a data chunk up to the next stage. Returns [constant @GlobalScope.OK] if the poll is successful but the load operation has not finished yet (intermediate stage). This means [method poll] will have to be called again until the last stage is completed. Returns [constant @GlobalScope.ERR_FILE_EOF] if the load operation has completed successfully. The loaded resource can be obtained by calling [method get_resource]. Returns another [enum @GlobalScope.Error] code if the poll has failed.
Polls the loading operation successively until the resource is completely loaded or a [method poll] fails. Returns [constant @GlobalScope.ERR_FILE_EOF] if the load operation has completed successfully. The loaded resource can be obtained by calling [method get_resource]. Returns another [enum @GlobalScope.Error] code if a poll has failed, aborting the operation.
