The Curse of Monkey Island is a point-and-click adventure game. The SCUMM engine was also used in this Monkey Island installment but it was upgraded to a "verb coin" (modelled after Full Throttle), an interface that consisted in a coin-shaped menu, with three icons: a hand, a skull and a parrot, basically representing actions related to hands, eyes and mouth, respectively. These icons implied the actions Guybrush would perform with an object. The hand icon would usually mean actions such as picking something up, operating a mechanism or hitting someone, the skull icon was most used for examining or looking at objects and the parrot icon was used to issue Guybrush commands such as talking to someone or opening a bottle with his teeth. The inventory and actions were thus visible on click, rather than on the bottom of the screen as previous point-and-click games by Lucasarts.
The player controlled a white 'X' cursor with the mouse, that turned red whenever landing onto an object (or person) with which Guybrush could interact. Holding left click over an object, whether in or outside the inventory, would bring up the coin menu, while right clicking it would perform the most obvious action with this particular object. Right clicking a door, for example, made Guybrush attempt to open it, while right clicking a person meant talking to him or her.By: binford6001
