This function creates a collision circle. This is a shape that has a position and a radius and infinite height. Events will be triggered when a element enters or leaves it.

Tip

To visualize a colshape when writing scripts, use the client console command showcol.

OOP Syntax Help! I don't understand this!

• Method:ColShape.Circle(...)

Syntax

colshape|false createColCircle ( float fX, float fY, float radius )

Required Arguments

• fX: The collision circle's center point's X axis position.
• fY: The collision circle's center point's Y axis position.
• radius: The radius of the collision circle. Can not be smaller than 0.1.

Returns

• colshape|false: col-circle

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

Code Examples

Example 1 Example 2 (OOP)

server

This example displays a chat message when a player enters the colshape and allows the colshape to be created using a console command set_zone.

local theZone

local function shapeHit(hitElement, matchingDimensions)
    if (hitElement and getElementType(hitElement) == 'player' and matchingDimensions) then
        outputChatBox(getPlayerName(thePlayer).. " is in the zone!")
    end
end

function setZone(playerSource, commandName, fX, fY, fRadius)
    local fX, fY, fRadius = tonumber(fX), tonumber(fY), tonumber(fRadius)
    if (not fX) or (not fY) or (not fRadius) then
        outputChatBox("Syntax: /"..commandName.." [X] [Y] [Radius]", playerSource)
    else
        if (theZone) then
            destroyElement(theZone)
        end
        local tempCol = createColCircle(fX, fY, fRadius)
        addEventHandler("onColShapeHit", tempCol, shapeHit)
        outputChatBox("Zone has "..(theZone ~= nil and "moved" or "created").."!", playerSource)
        theZone = tempCol
    end
end
addCommandHandler("set_zone", setZone, false, false)
