FKiSS Actions

An Action is a command which is immediately executed. It could change a cel from mapped to unmapped or change its transparency. It could move an object to a new location or change the value of a variable. Actions cover a wide-range of functionality.

These actions set up alarms, which are events triggered when certain conditions occur, such as a timer going off.

timer randomtimer lettimer
iffixed ifmapped ifmoved
ifnotfixed ifnotmapped ifnotmoved
exitevent

These actions use labels that mark a block of actions to execute that block of actions from several different places.

gosub gosubrandom
goto gotorandom
repeat exitloop
exitevent

These actions control the visibility of a cel. A mapped cel is visible while an unmapped cel is not visible.
