axis:Set(1, 0, 0)
myItem:RotateAround(point, axis, -60, false)

// When setting the ray with multiple non-zero values, each value is

If the Item3D has any children items, they will also be rotated, and their offsets will be adjusted to maintain the same relative position to this item.

Parameters

Example

use Libraries.Interface.Item3D
use Libraries.Compute.Vector3

Vector3 vector

// This will rotate the item 90 degrees clockwise around a ray passing 
// through the item's center and pointing to the right.
vector:Set(1, 0, 0)
myItem:Rotate(vector, 90)

// This will rotate the item 45 degrees clockwise around a ray passing 
// through the item's center and pointing straight down.
vector:Set(0, -1, 0)

// When setting the vector with multiple non-zero values, each value is
// relative to each other. Since this vector is set with a larger x
// value than y value, this ray points mostly left and a little upwards.
vector:Set(3, 1, 0)
myItem:Rotate(vector, 45)

// Because the values are relative to each other, this code has the same
// effect as the last Rotate call we used (because the x value is still
// 3 times larger than the y value).
vector:Set(9, 3, 0)
myItem:Rotate(vector, 45)

Rotate(number rotateX, number rotateY, number rotateZ, number degrees)

This action will rotate the Item3D about an axis. The axis is essentially a ray that starts at the center of the item and points outward. The item will then rotate clockwise around that ray. The ray is defined using three numbers, representing which way it points on the x, y, and z planes, respectively. The item will be rotated by an angle given in degrees. If the Item3D has any children items, they will also be rotated, and their offsets will be adjusted to maintain the same relative position to this item.

Parameters

// relative to each other. Since this vector is set with a larger x
// value than y value, this ray points mostly left and a little upwards.
myItem:Rotate(3, 1, 0, 45)

// Because the values are relative to each other, this code has the same
// effect as the last Rotate call we used (because the x value is still
// 3 times larger than the y value).

Parameters

  • boolean accepts: True to set this Item to receive mouse events, or false to ignore them.

SetAccessibilityCode(integer newAccessibilityCode)

This action changes the accessibility code for this Item. This should be done with care because setting the accessiblity code to the incorrect type can cause accessibility to stop functioning or, in some cases, cause the program to crash.

// Because the values are relative to each other, this code has the same
// effect as the last Rotate call we used (because the x value is still
// 3 times larger than the y value).
vector:Set(9, 3, 0)
myItem:Rotate(vector, 45)

SetScale(number scaleX, number scaleY, number scaleZ, boolean scaleChildren)

This action takes a MouseEvent and distributes it to any MouseListeners, MouseMovementListeners, and MouseWheelListeners that have been added to this Item3D. This action will also set the event to the "handled" state.

Parameters

  • number scaleX
  • number scaleY
  • number scaleZ
  • boolean scaleChildren

Example

use Libraries.Interface.Item2D
use Libraries.Interface.Events.MouseEvent
use Libraries.Interface.Events.MouseListener
Item2D myItem
MouseListener listener
myItem:AddMouseListener(listener)
MouseEvent event
event:eventType = event:CLICKED_MOUSE
myItem:ProcessMouseEvent(event)

SetScaleX(number scale)

This action will scale the Item3D by the given values. If the boolean parameter is set to true, and if the Item3D has any children items, they will also be scaled, and their offsets will be adjusted to maintain the same relative position to this item. If the boolean parameter is set to false, only this Item will be scaled.

Parameters

  • number scale

Example

use Libraries.Interface.Item3D
Item3D myItem
myItem:Scale(5, 2, 1, false)

SetScaleX(number scale, boolean scaleChildren)

This action will scale the Item3D by the given values. If the Item3D has any children items, they will also be scaled, and their offsets will be adjusted to maintain the same relative position to this item.

Parameters

  • number scale
  • boolean scaleChildren

Example

use Libraries.Interface.Item3D
Item3D myItem
myItem:Scale(5, 2, 1)

SetScaleY(number scale, boolean scaleChildren)

This action will rotate all of the children of this Item3D clockwise about an axis passing through this item. The direction of the axis is represented by the given Vector3, and the children will be rotated by the given number of degrees.

Parameters

  • number scale
  • boolean scaleChildren

Example

use Libraries.Interface.Item3D
Item3D parentItem
Item3D child1
Item3D child2

parentItem:Add(child1)
parentItem:Add(child2)

Vector3 axis

// This will rotate the item's children 90 degrees clockwise around a ray passing 
// through the item's center and pointing to the right.
myItem:RotateChildren(1, 0, 0, 90)

// This will rotate the item's children 45 degrees clockwise around a ray passing 
// through the item's center and pointing straight down.
myItem:RotateChildren(0, -1, 0, 45)

// This will rotate the item's children 60 degrees counter-clockwise around a ray  
// passing through the item's center and pointing to the right.
myItem:RotateChildren(1, 0, 0, -60)

// When setting the ray with multiple non-zero values, each value is
// relative to each other. Since this vector is set with a larger x
// value than y value, this ray points mostly left and a little upwards.
myItem:Rotate(3, 1, 0, 45)

// Because the values are relative to each other, this code has the same
// effect as the last Rotate call we used (because the x value is still
// 3 times larger than the y value).
myItem:RotateChildren(9, 3, 0, 45)

SetScaleY(number scale)

This action will scale the Item3D by the values of the given Vector3. If the Item3D has any children items, they will also be scaled, and their offsets will be adjusted to maintain the same relative position to this item.

Parameters

  • number scale

Example

use Libraries.Interface.Item3D
use Libraries.Compute.Vector3
Item3D myItem
Vector3 vector
vector:Set(5, 2, 1)
myItem:Scale(vector)

SetScaleZ(number scale, boolean scaleChildren)

This action will rotate the Item3D about an axis. The axis is essentially a ray that starts at the center of the item and points outward. The item will then rotate clockwise around that ray. The ray is defined using three numbers, representing which way it points on the x, y, and z planes, respectively. The item will be rotated by an angle given in degrees. If the Item3D has any children items, they will also be rotated, and their offsets will be adjusted to maintain the same relative position to this item.

Parameters

  • number scale
  • boolean scaleChildren

Example

use Libraries.Interface.Item3D
Item3D myItem

// This will rotate the item 90 degrees clockwise around a ray passing 
// through the item's center and pointing to the right.
myItem:Rotate(1, 0, 0, 90)

// This will rotate the item 45 degrees clockwise around a ray passing 
// through the item's center and pointing straight down.
myItem:Rotate(0, -1, 0, 45)

// This will rotate the item 60 degrees counter-clockwise around a ray  
// passing through the item's center and pointing to the right.
myItem:Rotate(1, 0, 0, -60)

// When setting the ray with multiple non-zero values, each value is
// relative to each other. Since this vector is set with a larger x
// value than y value, this ray points mostly left and a little upwards.
myItem:Rotate(3, 1, 0, 45)

// Because the values are relative to each other, this code has the same
// effect as the last Rotate call we used (because the x value is still
// 3 times larger than the y value).
myItem:Rotate(9, 3, 0, 45)

SetScaleZ(number scale)

This action will rotate the Item3D about an axis represented by the first 3 given number values. The item will be rotated by an angle given in degrees. If the boolean parameter is set to true, and if the Item3D has any children items, they will also be rotated, and their offsets will be adjusted to maintain the same relative position to this item. If the boolean parameter is set to false, only this Item will be rotated.

Parameters

  • number scale

myItem:SetX(35.0)

SynchronizeNodes()

This action returns the current Layer3D that this Item3D is a part of in the Game libraries.

Update(number secondsSinceUpdate)

This action updates the item. It takes a number parameter that should indicate how many seconds have passed since the last time this action was called. This action does nothing in the Item class, but any class that inherits from Item may override it.

Parameters

  • number secondsSinceUpdate: The number of seconds that have passed since the last time Update was called.

Example

use Libraries.Interface.Item
use Libraries.System.DateTime

class Main is Item

    action Main
        // We'll use a DateTime object to count seconds.
        DateTime time
        number currentTime = time:GetEpochTime()
        number newTime = 0

        repeat while GetX() < 300
            // Check what the time is now.
            newTime = time:GetEpochTime()

            // Calculate how many seconds have passed, then call Update.
            Update( (newTime - currentTime)/1000 )

            // Store the old time.
            currentTime = newTime
        end
    end

    // Our update action will move our Item to the right at 200 units a second.
    action Update(number secondsSinceUpdate)
        SetX(GetX() + 200 * secondsSinceUpdate)
    end
end

UpdateAll(number secondsSinceUpdate)

This action calls the Update action on this Item and all Items that have been added to this item with the Add action.
