CreateColCircle
From Multi Theft Auto: Wiki
This function creates a collision circle. This is a shape that has a position and a radius and infinite height that you can use to detect a player's presence. Events will be triggered when a player enters or leaves it.
| Tip: To visualize a colshape when writing scripts, use the client console command showcol |

ServerThis 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 )
if ( fY and fX ) then -- check we've got all 3 args we need
local tempCol = createColCircle ( fX, fY, 10.0 ) -- create a col
if ( tempCol == false ) then -- did the col get created successfully?
outputConsole ( "Syntax is: set_zone <X> <Y>" ) -- 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
