This function creates a collision polygon. See Wikipedia for a definition of a polygon. The first set of X Y of this shape is not part of the colshape bounds, so can set anywhere in the game world, however for performance, place it somewhere within the polygon. It should be noted this shape is 2D. There should be at least 3 bound points set.
colshape createColPolygon ( float fX, float fY, float fX1, float fY1, float fX2, float fY2, float fX3, float fY3, ... )
- fX: The X position of the collision polygon's dummy point
- fY: The Y position of the collision polygon's dummy point
- fX1: The 1st X position of the collision polygon's bound point
- fY1: The 1st Y position of the collision polygon's bound point
- fX2: The 2nd X position of the collision polygon's bound point
- fY2: The 2nd Y position of the collision polygon's bound point
- fX3: The 3rd X position of the collision polygon's bound point
- fY3: The 3rd Y position of the collision polygon's bound point
- ... From the 3rd position you can have as many points as you require to create the colshape.
Returns a colshape element if successful, false if invalid arguments were passed to the function.
This example displays a chat message when a player enters the colshape and allows the colshape to be created using a console function set_zone.
theZone = false function shapeHit ( thePlayer ) outputChatBox ( getPlayerName ( thePlayer ) .. " is in the zone!" ) -- display a message in everyone's chat box end function setZone ( playerSource, commandName, fX, fY, fX1, fY1, fX2, fY2, fX3, fY3 ) --Remember that after the 3rd position you --can have as many points as you require to --create the colshape. if ( fY and fX and fX1 and fY1 and fX2 and fX3 and fY3 ) then -- check we've got the 8 args we need local tempCol = createColPolygon ( fX, fY, fX1, fY1, fX2, fY2, fX3, fY3 ) -- create a col if ( tempCol == false ) then -- did the col get created successfully? outputConsole ("Syntax is: set_zone <X> <Y> <X1> <Y1> <X2> <Y2> <X3> <Y3>")-- inform the user what the valid syntax is else if ( theZone ~= false ) then -- did we already have a zone? destroyElement ( theZone ) -- if so, destroy it else addEventHandler ( "onColShapeHit", theZone, shapeHit ) -- add a handler for the onColShapeHit event end theZone = tempCol -- and store the new zone we've made outputChatBox ( "Zone has moved!" ) -- and tell everyone end end end addCommandHandler ( "set_zone", setZone ) -- add a console function called set_zone that will trigger the function setZone
