When you want to make a transition from one camera view to another, you have a number of options. Cameras themselves have some variation in how they can make transitions between viewpoints, but when you want something a little fancier, something to indicate a metaphorical chapter change, perhaps, or denoting relocation or the passage of time, the Wiper provides a few additional effects.

There are a number of wipe styles – the Dreams “bokeh” effect (breaking the image up into colourful bubbles), a dissolve effect, linear and circular wipes. A number of tweaks allow you to do things like change the colour or direction and you can achieve interesting effects by using an Action Recorder to animate a wipe’s tweaks – maybe move the focus around – or combine several wipes – for example to send a few different coloured wipes chasing across the screen in sequence.

To create transitions between Scenes in a Dream, see the Doorway gadget, which has its own copy of most of the Wiper options in its “Wipe Effects” tab.

Example Tutorial (adapted from Media Molecule)

  1. Stamp a shape into your scene.
  2. Stamp a wiper.
  3. Stamp 2 timer gagdets.
  4. Stamp a signal manipulator.
  5. Tweak one of the timers to a target time of 7 seconds. (Leave the other at 5.)
  6. Connect the “timer finished (pulse)” output from both timers to the signal input on the signal manipulator’s tweak menu. (This would cause a pulse signal to reach the signal manipulator at 5 seconds and then again at 7 seconds if time were started.)
  7. Set the signal manipulator to “custom remapper”.
  8. Under edge mode, select “toggle output at ON”. (Now each input to the signal will switch the output between on and off.)
  9. Connect the signal manipulator’s output to the wiper’s power input.
  10. Tweak the style to “hole”.
  11. Select “track object” and link it to the shape (stamped in step 1).
  12. Start time and see what happens.

The different target times mean the wipe starts at 5 seconds and stops at 7 seconds. If you move the shape during the wipe process, the “hole” should follow it around. Try other wiper tweaks and get a feel for what each one looks like in action.

  1. Wipe Style
    Choose the shape of the wipe (that is the transition effect between scenes or levels)

    • Bokeh – the screen dissolves into random coloured circles of different sizes, resembling dozens of out-of-focus highlights. It’s a distinctive “Dreams” effect.
    • Dissolve – a more conventional, uniform fade effect.
    • Linear – the screen ‘wipes’ from one side to the other; the direction depends on tweaks 5 & 6.
    • Hole – a circle contracts from the edges of the screen down to a point (use either tweaks 5 & 6 or 7 to specify the centre of the circle).
    • Circular – a circle expands outwards from a point until it fills the screen from edge to edge (use either tweaks 5 & 6 or 7 to specify the centre of the circle).
  2. Wipe Colour
    The default of the wipe is black, but you can colour it here.
  3. Glow
    Set the wipe colour’s “glow” (doesn’t apply to Bokeh or Dissolve options).
  4. Softness
    Set the softness of the wipe effect.
  5. X Position / Direction
    Together the X Position and Y Position are used to set either the direction of the wipe (for a Linear Wipe) or the co-ordinates on which it is centred (Hole and Circular Wipes). The handle on the box between them allows them to be tweaked at the same time.
  6. Y Position / Direction
    See X Position / Direction above [5].
  7. Track Object
    For Hole and Circular Wipes, you can use this tweak to connect to an object in the Scene, which forces the wipe to centre on that object, if it is on screen. You might typically use this to centre the wipe on the player character or the doorway – see for example the ending of the mini-game ‘Please Hug Me’, which centres on the player to reinforce the sense of a lonely ending.
  8. Fading In Time
    The speed of the wipe animation as it transitions in.
  9. Fading Out Time
    The speed of the wipe animation as it transitions out.
  10. Wipe Amount
    Use this to set the amount of the wipe transition. TBA
  11. Transition Done
    Outputs a pulse when a wipe has completed – use this to trigger the next piece of logic, such a switch of camera and the continuation of your scene.
  12. Power
    This is where you turn the gadget on/off.
