Actions Documentation

Activate(Libraries.Interface.Events.BehaviorEvent event)

Returns true if rendering the focus event.

Parameters

Activate()

This action returns a default behavior for this paricular control. Some controls do nothing by default, like a TextBox that responds to different kinds of input. Others, however, have default behaviors, like a Button or a MenuItem. If there is no default behavior, this action returns undefined.

Add(integer index, Libraries.Interface.Item2D newItem)

This action adds a different Item2D into this one, storing the added Item2D at a specific index in the internal array.

Parameters

Example

use Libraries.Interface.Item2D

Item2D parentItem
Item2D child
parentItem:Add(0, child)

Add(Libraries.Interface.Item2D newItem)

This action adds a different Item2D into this one. This makes a few things happen. 1. The added item will get this item as its parent. 2. The added item's x and y coordinates will become relative to this Item. 3. Most actions on this Item will also affect the added Item.

Parameters

Example

use Libraries.Interface.Item2D

Item2D parentItem
Item2D child
parentItem:Add(child)

AddBehavior(Libraries.Interface.Behaviors.Behavior behavior)

This action adds a new Behavior to this Item.

Advance(number time)

This action is used to advance the item forward in time in physics space to synchronize it for time of impact solving. This action is used internally and users should not need to use this action. Attribute Parameter time The amount of seconds to advance the item forward in time

Parameters

  • number time

ApplyAngularImpulse(number impulse)

This action applies an angular impulse to this item. The units are in kilogram units squared per second. This modifies the angular velocity of this item. Physics must be enabled on this item before using this action.

Parameters

  • number impulse: The angular impulse in kilogram units squared per second

Example

use Libraries.Interface.Item2D

Item2D item
item:SetWidth(100)
item:SetHeight(100)
item:EnablePhysics(true)
item:ApplyAngularImpulse(80)

ApplyForce(Libraries.Compute.Vector2 force, Libraries.Compute.Vector2 point)

This action applies a force to this item at the passed point. The force is in kilogram units per second per second. The point is the screen coordinates where the point will be applied. If the point is not on the center of the item, then a torque will be introduced causing the item to rotate. Physics must be enabled on this item before using this action.

Parameters

Example

use Libraries.Compute.Vector2
use Libraries.Interface.Item2D

Item2D item
Vector2 force
Vector2 point

item:SetWidth(100)
item:SetHeight(100)
item:EnablePhysics(true)

force:Set(300, 350)
point:Set(100, 100)    // apply the force to the top right corner of the item

item:ApplyForce(force, point)

ApplyForceToCenter(Libraries.Compute.Vector2 force)

This action applies a force to this item at the center of the item. The force is in kilogram units per second per second. No torque is introduced to the item when using this action. Physics must be enabled on this item before using this action.

Parameters

Example

use Libraries.Compute.Vector2
use Libraries.Interface.Item2D

Item2D item
Vector2 force

item:SetWidth(100)
item:SetHeight(100)
item:EnablePhysics(true)

force:Set(300, 350)

item:ApplyForce(force)

ApplyLinearImpulse(Libraries.Compute.Vector2 impulse, Libraries.Compute.Vector2 point)

This action applies a linear impulse to this item at the passed point. The impulse is in kilogram units per second. This immeadietly modifies the linear velocity of this item. The point is the screen coordinates where the impulse will be applied. If the point is not the center of the item, then the angular velocity of this item will also be modified. Physics must be enabled on this item before using this action.

Parameters

Example

use Libraries.Interface.Item2D
use Libraries.Compute.Vector2

Item2D item
Vector2 impulse
Vector2 point

item:SetWidth(100)
item:SetHeight(100)
item:EnablePhysics(true)

impulse:Set(100)
point:Set(100, 100)     // apply the impulse to the top right corner

item:ApplyLinearImpulse(impulse, point)

ApplyTorque(number torque)

This action applies a torque to this item. The units are kilogram units squared per second per second. Physics must be enabled on this item before using this action.

Parameters

  • number torque: The torque to apply to this item in kilogram units squared per second per second

Example

use Libraries.Interface.Item2D

Item2D item
item:SetWidth(100)
item:SetHeight(100)
item:EnablePhysics(true)
item:ApplyTorque(350)

AreChildrenProcessingMouseEvents()

This action returns whether or not this Item is allowing its children to receive mouse events if the Item is custom drawing. If the Item isn't using custom drawing, this value is irrelevant -- children objects always receive mouse events before the parent if the parent isn't performing custom drawing.

Return

boolean:

BeginCollision(Libraries.Interface.Item item)

This action is used to indicate that two items have just begun colliding. When two Items collide, the BeginCollision action should be called on both of them, with the other item passed as a parameter to the action. Note that this action does nothing by default, but classes that inherit from Item may override it.

Parameters

Example

use Libraries.Interface.Item

Item collider1
Item collider2
collider1:BeginCollision(collider2)
collider2:BeginCollision(collider1)

BeginMouseOver()

This action is used when a control is moused over by the mouse.

CalculateDefaultFocusOrdering()

Forms by default can calculate a default ordering for focus across a set of controls. This means that if this action is called, the system will dig through the form that is being created and calculate such an order. This action is intentionally limited and, while it works for default cases and typical controls, callers should recognize that complex or highly custom forms will likely require additional work. Put another way, focus orderings are typically not one size fits all, even if this action tries to calculate sensible defaults under many common conditions.

CanRotate(boolean flag)

This action gets the position of the center of this item in global (world) coordinates.

Parameters

  • boolean flag

CancelBehaviors()

This action stops all behaviors this Item is following without finishing them.

CenterAlignContent()

This action aligns any content in the control to the center.

CenterAlignTitle()

This action aligns the title on the form control to the center.

ChangeButtonIcon(text name, text fileName)

This action changes the icon(image) on a button in the control. This action should only be used when the button is created and displayed on the form (after form:Display() is called).

Parameters

  • text name: The text name identifying the button.
  • text fileName: The path of the image to use as the button icon.

Example

use Libraries.Interface.Events.BehaviorEvent
use Libraries.Interface.Forms.FormBehavior
use Libraries.Interface.Forms.Form
