Effects

The ready-made animations. In the web editor they are the bars you add with + Effect; in a hologram file they are named by their id, with optional settings in brackets: spin(period=40)@icon.

Effects that play once

Effect	Id	What it does	Settings
Pop in	pop-in	Grows from nothing, with a little bounce	duration
Pop out	pop-out	Shrinks to nothing, and stays hidden	duration
Fade in	fade-in	Text slowly shows	duration
Fade out	fade-out	Text slowly hides, and stays hidden	duration
Slide up	slide-in	Rises into place while it shows	distance, duration
Shake	shake	Shakes side to side	amount, duration
Wiggle	wiggle	Wobbles like saying hi	angle, duration
Bounce	bounce	Jumps and lands	height, duration
Typewriter	typewriter	Text appears letter by letter	duration
Count up	count-up	Every number in the text counts up from zero	duration

Effects that repeat

Effect	Id	What it does	Settings
Float	bob	Goes gently up and down	amplitude, period
Spin	spin	Turns round and round	period, axis (x, y, z)
Heartbeat	pulse	Grows and shrinks a little	amount, period
Rainbow	rainbow	Text changes colour	period
Glow	glow-pulse	The glow gets stronger and weaker (layers with a glow colour)	period, min

Durations and periods are in ticks (20 ticks are 1 second), distances and heights in blocks, angles in degrees.

How effects combine

Effects on the same layer add up: positions and angles add, size and opacity multiply. A float and a bounce together go up and down more; a pop in over a heartbeat grows while it beats.

An effect that ends somewhere other than where it started, like pop out or fade out, holds its last frame: the layer stays hidden until another effect of the same kind (a pop in, a fade in) takes over. That is what lets a hologram stay hidden after a player walks away.

In the web editor

• In Always, a repeating effect fills the whole row. Stretching it makes it slower; its settings choose how many times it repeats in the bar.
• In the other moments, place the bar where it should happen; stretching changes how long it takes.
