*'''pi''': i was nice enough to provide this so you could save the effort of typing ''math.pi''.

*'''me''': the reference to the object currently having its script executed. For example, an object may use ''me.x'' within its script to retrieve its x position.  
−
*'''eps''': 'epsilon', basically a small number which is used to make floating-point comparisons a little more reliable. Basically, instead of doing ''x == y'', you'll do ''abs(x - y) < eps''. By default, it's '''.0001''' (or close enough to). However, you should  avoid floating-point comparisons whenever possible.

*'''other''': the reference to the other object involved in an event, usually collisions. Note that this variable becomes valid only in certain cases.

*'''fps''': returns the current fps.

*'''player''': refers to the player object.
−
*'''basefps''': returns the 'ideal' fps, which is set in the game options.  
+
*'''selected''': a special reference that actually references more than one object. It performs a given action to each of its instances individually. Like '''other''', it is only valid in certain cases; namely only after using '''select()''', and becomes invalid at the end of the calling object's event.
−
*'''timer''': the in-game clock, if it is being used in the level; if it isn't, it's '''false'''. Counts down by one approximately every real second.
 
−
*'''timertick''': increments by 1 each time the main loop finishes, and wraps around back to 0 when it equals '''fps'''; at that point, it decrements '''timer''' by 1.
 
−
*'''counter''': incremented by 1 each time the main loop finishes; ie. it's tied to the framerate. It does not wrap at a certain point, but continues counting.

The following is a list of functions and keywords used by MPUZ's engine.

Keywords and Global Variables

Object references

For a breakdown of the variables contained in the object structure, check out MPUZ: Object Variables.

  • me: the reference to the object currently having its script executed. For example, an object may use me.x within its script to retrieve its x position.
  • other: the reference to the other object involved in an event, usually collisions. Note that this variable becomes valid only in certain cases.
  • player: refers to the player object.
  • selected: a special reference that actually references more than one object. It performs a given action to each of its instances individually. Like other, it is only valid in certain cases; namely only after using select(), and becomes invalid at the end of the calling object's event.
