Movement speed

Appearance

 GetPersonOffsetX(name)
     - gets the horizontal offset used for blitting frames

 SetPersonOffsetX(name, x)
     - sets the horizontal offset to use for blitting frames
       e.g. setting it to 10 would result in the person frame blitted always 10 pixels
       to the right, while the person's x-position would remain unchanged.

 GetPersonOffsetY(name)
     - gets the vertical offset used for blitting frames

 SetPersonOffsetY(name, y)
     - sets the vertical offset to use for blitting frames
       e.g. setting it to 10 would result in the person frame blitted always 10 pixels 
       to the bottom, while the person's y-position would remain unchanged.
  • GetPersonAngle(name): Get the rotation angle of the person name.
  • SetPersonAngle(name, angle): Set the rotation angle of person name to angle radians.
  • SetPersonScaleFactor(name, scale_w, scale_h): Rescales the sprite of person name by relative factors scale_w and scale_h.
  • SetPersonScaleAbsolute(name, width, height): Rescales the sprite of person name to width * height pixels.
  • IsPersonVisible(name): Check if the person with name is visible or not. true: visible, false: not visible.
  • SetPersonVisible(name, visible): Make person name visible or invisible. true: visible, false: not visible.

Obstruction

 GetObstructingTile(name, x, y)
   - returns -1 if name isn't obstructed by a tile at x, y,
   - returns the tile index of the tile if name is obstructed at x, y

 GetObstructingPerson(name, x, y)
   - returns "" if name isn't obstructed by person at x, y,
   - returns the name of the person if name is obstructed at x, y

 IgnorePersonObstructions(person, ignore)
   - Sets whether 'person' should ignore other spriteset bases
 
 IsIgnoringPersonObstructions(person)
   - Returns true if 'person' is ignoring person obstructions, else false

 GetPersonIgnoreList(person)
   - Returns a list of people that 'name' is ignoring
 
 SetPersonIgnoreList(person, ignore_list)
   - Tells 'person' to ignore everyone in ignore_list
   e.g. SetPersonIgnoreList("White-Bomberman", ["bomb", "powerup"]);
   Tells White-Bomberman to not be obstructed by bombs or powerups

Talk interaction

 SetTalkActivationKey(key)
 GetTalkActivationKey()
   - set key used to activate talk scripts

 SetTalkDistance(pixels)
 GetTalkDistance()
   - set distance to check for talk script activation

Following other persons

  • FollowPerson(name, leader, pixels): Makes a sprite follow behind another sprite.

Person data

 GetPersonData(name)
   - gets a data object assiocated with the person 'name'
   There are certain default properties/values filled in by the engine, they are:
   num_frames - the number of frames for the person's current direction
   num_directions - the number of directions for the person
   width - the width of the spriteset's current frame
   height - the height of the spriteset's current frame
   leader - the person that this person is following, or "" if no-one...
   Any other properties are free for you to fill with values,
   e.g.
     var data = GetPersonData("Jimmy");
     var num_frames = data["num_frames"];
 
 SetPersonData(name, data)
   - sets the 'data' object assiocated with the person 'name'
   e.g.
   var data = GetPersonData("Jimmy");
   data["talked_to_jimmy"] = true;
   SetPersonData("Jimmy", data);

 SetPersonValue(name, key, value)
   - SetPersonValue("Jimmy", "talked_to_jimmy", true); // same as code above
 
 GetPersonValue(name, key)
   - GetPersonValue("Jimmy", "num_frames"); // same as previous code above
