The technical scheme of the invention discloses a resource hot-loading rapid iteration game making system and method. The method comprises the following steps: identifying and converting a source file provided by a game developer, and loading identified and converted file data into a memory block; representing the file data loaded into the memory block by a file list, performing real-time monitoring, acquiring change information when the file list changes, and transmitting the change information; producing a mapping table for the monitored data file and unique identifiers of the data file, receiving the change information, acquiring the changed data file through the mapping table, reloading the data file into the memory block, and issuing a reloading instruction; receiving and executing a reloading instruction issued by a monitoring module, acquiring a new data file, and rebinding file resources included in the data file into a game system. The resource hot-loading rapid iteration game making system and method have the beneficial effects that the game development period is shortened greatly, the experience and performance of a game are improved, personnel in various positions can share out the work and cooperate with one another conveniently, and the flow is optimized.
