Abstract: A method for virtual object control in a game application includes detecting a first virtual resource transfer operation when a distance between a first virtual object and a first virtual obstacle is less than or equal to a first predetermined distance threshold. The first virtual object is located in a first virtual region, the first virtual obstacle is in a first locked state that prevents the first virtual object from entering a second virtual region. Then, the method includes switching the first virtual obstacle from the first locked state to a first unlocked state that allows the first virtual object to enter the second virtual region based on a reduction of virtual resources from the first virtual object. Then, the method includes controlling the first virtual object to enter the second virtual region when a first control operation is detected. Apparatus and non-transitory computer-readable storage medium counterpart embodiments are contemplated.
