Information processing program, information processing device, information processing system, and information processing method

An information processing system configured to control movements of an object in a virtual three-dimensional space, the information processing system comprising:

• a processor;
• and
• a memory configured to store computer readable instructions that, when executed by the processor, cause the information processing system to:
• control the movements of the object;
• determine switching of the movement of the object between a three-dimensional movement in the virtual three-dimensional space and a movement along a plain surface provided in the virtual three-dimensional space;
• and
• determine a speed of the object after the switching on the basis of a speed of the object before the switching when the switching between the three-dimensional movement in the virtual three-dimensional space and the movement along the plain surface is performed, wherein
• when the object switches from the movement along the plain surface to the three-dimensional movement, the speed component along the plain surface before the switching is used as the speed component with respect to the plain surface of the three-dimensional movement after the switching, and
• when the object moves along the plain surface, the object is displayed in a plain surface manner causing the object to be absorbed to the plain surface.

An information processing method for controlling movements of an object in a virtual three-dimensional space, the information processing method comprising:

• controlling the movements of the object;
• determining switching of the movement of the object between a three-dimensional movement in the virtual three-dimensional space and a movement along a plain surface provided in the virtual three-dimensional space;
• and
• determining a speed of the object after the switching on the basis of a speed of the object before the switching when the switching between the three-dimensional movement in the virtual three-dimensional space and the movement along the plain surface is performed, wherein
• when the object switches from the movement along the plain surface to the three-dimensional movement, the speed component along the plain surface before the switching is used as the speed component with respect to the plain surface of the three-dimensional movement after the switching, and
• when the object moves along the plain surface, the object is displayed in a plain surface manner causing the object to be absorbed to the plain surface.
