This invention relates to the field of game development technology, and more particularly to a large-map game development system based on multi-level task interaction. The system includes a large-map scene parsing module, a task hierarchy association module, a task-map association interaction module, and a large-map interaction development module. The game development engine uses the scene parsing module to perform topological deconstruction of the original large-map materials, generating a map topology dataset. Based on the map topology dataset, a multi-level task interaction framework is constructed and bound, generating a task-map association dataset. Based on the task-map association dataset, the interaction trigger conditions for each task node are configured, generating a task interaction rule set. The map topology dataset, task hierarchy association table, task-map association dataset, and task interaction rule set are integrated and compiled to form a large-map game interaction program. This invention clarifies the specific rules for game players to trigger and complete tasks in different map areas and different scene levels.
