When a trigger happens, the sentence checks its conditions and runs its actions.

These run when you click with the pointer. A finger tap on a phone is a click too. On a scene, they run for clicks on empty spots that no object takes. During playback, you can’t click an object whose opacity is 0, and the click passes through to what’s below it. If you need an invisible spot to click, remove its fill instead of lowering its opacity.

• On clickWhen you press and release
• On double clickWhen you press twice quickly
• On long pressWhen you hold for 0.5 seconds without moving

Each runs once at that moment and doesn’t hold anything. Moving the pointer from the object onto another object inside it doesn’t count as entering or leaving. Entering and leaving also work only with a mouse.

• On pointer enterWhen the pointer comes into the object
• On pointer leaveWhen the pointer goes out of the object
• On pointer downWhen a press starts
• On pointer upWhen you let go

This runs when you press, drag more than 50 pixels on the screen in one direction, and let go. In the menu, choose On swipe left, On swipe right, On swipe up, or On swipe down. On an object, it takes only swipes that start on that object. On a scene, a left or right swipe runs instead of the usual swipe that changes scenes on the presentation screen.

On scene enter runs every time this scene opens during playback. After a delay runs once when the set number of seconds has passed after the scene opens, and leaving the scene before then cancels it. The default is 1 second. Click the number to change it, for example to 0.5. Use it for screens that move on by themselves, like a kiosk.

These run when an animation has played to the end, or when the clock reaches a stop. Along with an unnamed item, the menu lists each animation and stop of the object’s frame (or of the scene, outside a frame). On a frame, the unnamed item waits for all of the frame’s animations. On a scene, it waits only for the timeline and the auto-play animations. To wait for an effect another sentence played, choose its name.

These run when a video or audio clip in the same scene has played to the end, or when it passes the seconds you set. Only clips with Sync to Timeline turned off in the Video or Audio panel appear in the menu. In a sentence on the clip itself, the clip shows as “media”. Other clips show by name under Other media. A looping clip never ends, so its end trigger never happens either.

This runs when a variable’s value changes during playback. At the bottom of the menu, each variable you made gets its own item, like “When score changes”. It happens when an action or a request puts in a value, not when you edit the value in the Variables panel.

At the top of the menu, every scene except the current one gets its own item, like “Go to New Scene”. Scenes with the same name can’t be told apart in the menu, so rename your scenes first (see Work with scenes). It doesn’t go to a hidden scene.

Next scene and Previous scene skip hidden scenes and go to the scene after or before. On the last scene, Next scene does nothing. Back returns to the scene you left with Go to a scene. Moves made with Next scene or Previous scene aren’t remembered. End show ends in a different way depending on where the show is viewed.

Plays or stops a named animation. The menu lists the animations of the object’s frame (the object itself if it’s a frame, or the scene outside a frame) as items like “Play Pop”. Those of other frames or the scene are under Other animations. A played animation runs to the end and then returns to the original look. If the changed look should stay, use a Set state action.

• Stop the animationReturns to the original look on the spot
• Run it again at a stopKeeps playing to the next stop

Moves a frame to one of its states, and shows in the menu as items like “Set state state2”. A state keeps its look until you move to another state. So even in a While hovering sentence, it doesn’t go back when the pointer moves away. If the frame is already in that state, nothing happens. To make states, see Make buttons with frame states.

Plays or pauses the scene’s timeline, or moves it to a stop or to a time in seconds. It doesn’t move frames’ animations.

Plays or pauses a video or audio clip in the same scene, or moves it to a time in seconds. As with the triggers, only clips with Sync to Timeline turned off appear in the menu. In a sentence on the clip itself, it shows right away as “media”. In a sentence on another object, such as a button, it shows by clip name under Other media. The play item looks like an animation item (“Play media”), but it plays the clip, not an animation.

Opens a web address in a new tab. When you choose it, the field opens with the default https:// all selected, so type the address starting with https://, like “https://www.example.com”. If you leave out https:// and type only “example.com”, it’s added to the address of the page you’re on, and the wrong page opens. It opens only http and https addresses, mailto: email addresses, and tel: phone numbers, and skips other formats. Wrap a variable name in double curly braces in the address, like {⁠{score}⁠}, and it’s replaced with that value during playback. It doesn’t open from a sentence triggered with the phone remote.

Sends a named message. Every On message sentence with the same name runs along with it, wherever it is in this scene, so use it to move several objects at once with one button. The default name is message.

Sends a request to a web service and puts the answer in a variable. The next action waits until the answer arrives. Choosing it opens the Request panel. For how to use it, see Requests and variables.

Each variable gets the items that fit its type, like “Increase score”. Every variable can be set to a value, and choosing that item opens the field with the current value in it. You don’t type the value of a Boolean variable: each click switches it between true and false.

• Increase or decreaseA number variable, by 1
• Toggle a variableFlips a Boolean variable between true and false
• Set a valueTo the value you type

Returns every variable changed during playback to the value saved in the Variables panel. Use it to start a quiz over from the beginning.

Runs only when a frame is in a certain state. In a sentence on a frame or on an object inside it, that frame’s states show right away, like “if in open”. Other frames’ states are under Other states. To open and close with the same button by turns, give two sentences different state conditions.

With several conditions on one sentence, all of them must be met for it to run. To run when either one is met, make another copy of the sentence with ⋯ › Duplicate, then click the condition word in the copy and change only the condition. If both conditions are met at once, both sentences run, and the actions happen twice. In the preview log, sentences skipped because of a condition show dimmed, with the values at that moment (Edit and preview).
