Program, game control method, and information processing apparatus

A game control method performed by an information processing apparatus, comprising:

• causing a first object arranged on a field object in a virtual space in which a world coordinate system having a first axis and a second axis is set to be displayed on a screen in which a screen coordinate system having a third axis and a fourth axis is set;
• detecting a first user operation;
• detecting first and second positions on the screen according to the first user operation while the first user operation is being detected;
• moving the first object relatively to the field object in the virtual space according to the detected first user operation, wherein a speed and a direction of moving the object are determined based on a distance between the first position and the second position;
• moving the first object while changing at least one of a first speed component and a second speed component of the first object when an end of the first user operation is detected;
• and
• relating, based on a mapping interaction function, a pair of objects including the first object and a second object, and executing particularized processing including both the first object and the second object, wherein relating the pair of objects and executing particularized processing comprises:
• updating an area of the field object in which the first object is arranged, and determining that the second object is present in the area;
• determining, an area type of the area of the field object in which the first object is arranged;
• determining, based on the area type, a valid gameplay interaction type corresponding to the area type;
• and
• pairing the first object and the second object and initiating a first gameplay interaction specific to the first object and the second object.

An information processing apparatus that executes a game, comprising:

• a display unit that displays a screen;
• and
• a control unit,
• wherein the control unit:
• causes a first object arranged on a field object in a virtual space in which a world coordinate system having a first axis and a second axis is set to be displayed on a screen in which a screen coordinate system having a third axis and a fourth axis is set;
• detects a first user operation;
• detects first and second positions on the screen according to the first user operation while the first user operation is being detected;
• moves the first object relatively to the field object in the virtual space according to the detected first user operation, wherein a speed and a direction of moving the first object are determined based on a distance between the first position and the second position;
• moves the first object while changing at least one of a first speed component and a second speed component of the first object when an end of the first user operation is detected;
• and
• relates, based on a mapping interaction function, a pair of objects including the first object and a second object, and executes particularized processing including both the first object and the second object, wherein relating the pair of objects and executing particularized processing comprises:
• updating an area of the field object in which the first object is arranged, and determining that the second object is present in the area;
• determining, an area type of the area of the field object in which the first object is arranged;
• determining, based on the area type, a valid gameplay interaction type corresponding to the area type;
• and
• pairing the first object and the second object and initiating a first gameplay interaction specific to the first object and the second object.
