Abstract: A peripheral area is provided on the periphery of an operation target (for example, a player character) of a user. When an object (for example, a bullet) is located on the periphery of the operation target (for example, passes therethrough), an effect different from that when the object touches the operation target (for example, hits it) is generated. A form of the peripheral area may be changed. In a case where a predetermined condition regarding the operation target is satisfied, the form thereof may be changed. When the object is located on the periphery of the operation target, a parameter different from a parameter varying when the object touches the operation target may be changed When the object located on the periphery of the operation target, a second value may be added to a first value associated with the operation target.

Abstract: A system for changing appearance of a character composed of a plurality of models judges whether a model can be changed or not on the basis of whether an adjacency condition is satisfied or not. Whether the adjacency condition is satisfied or not is judged on the basis of a shape of a judgement target and a shape of a model adjacent to a change target. The system may refer to a type of a shape set to each model to judge whether the adjacency condition is satisfied or not. The system may also refer to a type regarding a portion adjacent to another model set to each model for the judgement. Moreover, the system may adjust a shape of an adjacent model on the basis of information that is set to the model.

Abstract: A non-transitory computer-readable medium including a video game processing program product for causing a server to realize functions to control progress of a video game in response to an operation of a user is provided. The functions include: a first setting function configured to set an ability to an available state when a predetermined available condition for the ability is satisfied, the ability being associated with an in-game element in the video game; and a second setting function configured to set a combination ability to an available state, the combination ability corresponding to a combination of an in-game element selected by the user and the ability that has become the available state by the setting of the first setting function.
