# CreateColTube

This function creates a collision tube. This is a shape that has a position and a 2D (X/Y) radius and a height. See Cylinder for a definition of a tube. A tube is similar to a colcircle, except that it has a limited height, this means you can limit the distance above the position defined by (fX, fY, fZ) that the collision is detected.

 [[{{{image}}}|link=]] Tip: To visualize a colshape when writing scripts, use the client console command showcol

## Syntax

```colshape createColTube ( float fX, float fY, float fZ, float fRadius, float fHeight )
```

OOP Syntax Help! I don't understand this!

Method: ColShape.Tube(...)

### Required Arguments

• fX: The position of the base of the tube's center on the X axis
• fY: The position of the base of the tube's center on the Y axis
• fZ: The position of the base of the tube's center on the Z axis
• fHeight: The collision tube's height

### Returns

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

Server

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, fZ )
if ( fZ and fY and fX ) then -- check we've got all 3 args we need
local tempCol = createColTube ( fX, fY, fZ, 10.0, 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
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
