Information processing apparatus having dual modes of video game object launch, and counterpart method and system
An information processing apparatus includes controlling movement of any of first objects arranged on a field, controlling movement of a second object fed to any of the first objects, and carrying out control such that a first object satisfying prescribed proximity relation with the second object among the first objects acquires the second object. The controlling movement of a second object includes ejecting the second object to the field from a prescribed position in a direction determined based on an accepted first user operation input and moving the second object over the field in accordance with an accepted second user operation input. The controlling movement of any of the first objects moves any of the first objects toward the second object ejected to the field and moves any of the first objects toward the second object that moves over the field.
