Description

Bullet behavior scheduling method and device, equipment and medium thereof Technical Field The application relates to the technical field of game interaction, in particular to a bullet behavior scheduling method and device, equipment and medium thereof. Background In the field of game development, the run-time behavior (including movement trajectories, collision detection, hit response, etc.) of bullets in a bullet screen system directly affects the fluency and playability of a battle. At present, the main stream scheme adopts a traditional hard coding mode, and logic such as bullet initialization, movement, collision, hit, destruction and the like is directly solidified in a program code. Under the scheme, a programmer is required to write a large number of repeated codes for each newly added bullet behavior (such as tracking, rebound and splitting), and bullet logic is scattered among the modules, so that the code coupling degree is high and the maintainability is poor. Meanwhile, the planner cannot independently adjust bullet behavior parameters or combine new behaviors, each modification depends on programmer intervention to reconstruct, compile and test codes, the iteration period is long, and the trial-and-error cost is high. In addition, the existing scheme relies on a general physical system of a game engine to perform collision detection, and an independent physical component is created for each bullet, so that the memory expense is high, the CPU load is high, and the frame rate is seriously reduced when a large number of bullets are on screen. Collision callbacks of a physical engine are generated in asynchronous threads, the time sequence is uncontrollable, hit judgment is often delayed or the sequence is disordered, and accurate frame synchronization logic is difficult to realize. Meanwhile, bullet entities and special effect resources are frequently created and destroyed, and multiplexing mechanisms such as an object pool and the like are lacked, so that memory fragments and garbage are recovered and blocked, and a large-scale bullet screen scene cannot be supported. The logics such as bullet initialization, movement, collision and destruction are mixed together, collision detection is tightly coupled with other behaviors, independent optimization or replacement cannot be realized, and expansibility is poor. In summary, the existing bullet behavior scheduling schemes have the problems of behavior logic coupling, poor expansibility, disordered resource management, bottleneck in collision detection performance, uncontrollable time sequence and the like, and are difficult to meet the requirements of smoothness, accuracy and expandability in large-scale bullet screen scenes.
