This function creates a collision sphere. This is a shape that has a position and a radius. See Wikipedia for a definition of a sphere.

Syntax

colshape createColSphere ( float fX, float fY, float fZ, float fRadius )

Required Arguments

  • fX: The collision sphere's center point's X axis position
  • fY: The collision sphere's center point's Y axis position
  • fZ: The collision sphere's center point's Z axis position
  • fRadius: The collision sphere's radius

Returns

Returns a colshape element if successful, false if invalid arguments were passed to the function.

Example

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

addCommandHandler ( "set_zone", "setZone" ) -- add a console function called set_zone that will trigger the function setZone
function setZone ( playerSource, commandName, fX, fY, fZ )
    if ( fZ and fY and fX ) then -- check we've got all 3 args we need
        local tempCol = createColSphere ( fX, fY, fZ, 10.0 ) -- create a col
        if ( tempCol == false ) then -- did the col get created successfully?
            outputConsole ( "Syntax is: set_zone <X> <Y> <Z>" ) -- 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
            end
            theZone = tempCol -- and store the new zone we've made
            outputChatBox ( "Zone has moved!" ) -- and tell everyone
        end
    end
end

addEventHandler ( "onColShapeHit", getRootElement(), "shapeHit" ) -- add a handler for the onColShapeHit event
function shapeHit ( thePlayer ) 
    outputChatBox ( getClientName ( thePlayer ) .. " is in the zone!" ) -- display a message in everyone's chat box
end
