Usage

Sample capx

Set boundaries

• Horizontal

  • Enable

    • Set property Horizontal to Yes, or
    • Action:Horizontal boundary enable
    • Expression:HorizontalEnable

  • Boundaries

    • Property Left, property Right, or

    • Action:Set horizontal boundary, or

    • Action:Set horizontal boundary to

      • Pin boundaries on an object

    • Expression:LeftBound, Expression:RightBound

• Vertical

  • Enable

    • Set property Vertical to Yes, or
    • Action:Vertical boundary enable
    • Expression:VerticalEnable

  • Boundaries

    • Property Top, property Bottom, or

    • Action:Set vertical boundary, or

    • Action:Set vertical boundary to

      • Pin boundaries on an object

    • Expression:TopBound, Expression:BottomBound

Mode

When position is out of boundary

• Property Mode

  • Clamp : clamp position in the boundary

    • Property Align

      • Boundaries : align boundaries box of this object to reached boundary
      • Origin : set position to reached boundaries

  • Wrap

    • Property Align

      • Boundaries : align boundaries box of this object to opposite boundary

        • This behavior is similar with official wrap behavior

      • Origin : set position to opposite boundary

  • Mode wrap (sample capx)

    • Property Align

      • Boundaries : not supported
      • Origin : set position to opposite boundary with an offset to keep the moving distance

• Triggers

  • Condition:On hit any boundary

  • Condition:Is hit boundary

  • Horizontal

    • Condition:On hit left boundary
    • Condition:On hit right boundary

  • Vertical

    • Condition:On hit top boundary
    • Condition:On hit bottom boundary

Position and percentage

Position --> percentage

• Expression:HorPercent : ( inst.X - left ) / ( right - left )

  • Expression:HorScale : map Expression:HorPercent to another value

• Expression:VerPercent : ( inst.Y - top ) / ( bottom - top )

  • Expression:VerScale : map Expression:VerPercent to another value

Percentage --> position

Sample capx

• Expression:HorPercent2PosX : percentage --> X
  
• Expression:HorPercent2PosY : percentage --> Y
