Entry effects: designing the moment someone walks into a room

When someone joins a live or voice room, the entry effect is the room's way of saying who just walked in. Done well, it gives the host a cue to greet a regular and gives a VIP something visible for their status; done badly, it hides the stream every time a friend reconnects.

This guide works through the decisions behind a good arrival, using the real files in our Entry Effects collection.

What an entry effect is actually for

An entrance does three jobs at once:

• It announces. Everyone in the room learns that someone has arrived, usually without reading anything.

• It signals status. Entrances are almost always tied to a VIP tier, a level or a purchase, so the effect itself is the privilege.

• It prompts a response. Hosts greet people by name when they see a big arrival, and that greeting is often the real value of the feature.

Keep those jobs in mind and most design questions answer themselves. If an effect runs so long that the host stops talking and waits for it to finish, it has failed at the third job.

The three layers of an arrival

Most apps build an arrival from more than one animation:

1. The stage or full-screen effect: the vehicle, creature or scene that plays over the room.

2. An entry notice bar: a slim banner carrying the user's name and avatar, so people know who it is.

3. A seat moment: a smaller effect when that user takes a mic seat.

The notice bar matters more than people expect. A supercar crossing the screen tells the room that someone important arrived; only the bar tells them which person. The VIP Broadcast & Entry Pack has VIP entry notices alongside gift broadcasts, and the SVIP Entrance & Notice Pack covers SVIP entrance bars Lv 1–5 and online notices 7–12, in both LTR and RTL.

How long should an entrance run?

The 14 entrances in the collection run from 3 seconds to 10 seconds. Here is a cross-section:

A practical rule: match length to rarity. Short entrances of three to four and a half seconds suit tiers that many users hold, because they will fire often. The ten-second pieces earn their time when they belong to a top tier that only a few people in any room will have.

Whatever you choose, plan for collisions. When several people join at once, queue entrances rather than stacking them, cap the queue, and fall back to the notice bar alone once it is full. A user who reconnects after a dropped connection should not trigger the full effect again within a short window.

Canvas and shape

The collection mixes two shapes:

• Full-height portrait pieces, such as Wedding Bicycle Ride and Neon Trail Motorbike at 750x1624, or Lightning Hot Rod at 750x1334. These are made to cover the room.

• Stage pieces, such as Frost Spirit Wolf at 400x400, Luxury Yacht Cruise at 512x512 and Red Supercar Arrival at 750x750. These play in a band across the screen and leave the host's video or the seat grid partly visible.

In a voice room, where the seat grid is the content, a stage piece often works better than a full cover. In a video room, a portrait effect that clears quickly can feel more cinematic. Either way, set the scale mode (fit or fill) per shape rather than per file, so every arrival behaves consistently.

File size is not about the canvas

It is tempting to assume that a bigger canvas means a bigger file. The collection shows otherwise: Lightning Hot Rod is 750x1334 and 334 KB, while Golden Phoenix Rise is 450x800 and 8.34 MB. Across all 14 entrances, sizes run from 334 KB to 8.34 MB, with a median of 1.06 MB.

The difference comes from how SVGA stores animation. A file holds a set of bitmap images plus per-frame transforms for each sprite. An effect built from a few images that move, scale and fade stays small; one built from many painted frames carries far more images and grows quickly.

For developers this leads to one firm rule: never download an entrance at the moment a user joins a room. Fetch it when the user earns or buys the tier, cache it on the device, and have the room play only local files.

Sound in a voice room

Seven of the 14 entrances carry audio inside the file. In a video stream that adds impact; in a voice room it plays over whoever is speaking. Sensible defaults:

• Duck or mute effect audio while any mic seat is live.

• Give users a setting to turn effect sounds off.

• Never let one entrance's sound overlap another's.

Vehicles, ride-ins and creatures

Most of the collection falls into three groups. Supercars and bikes read instantly as status and are the safest choice for general VIP tiers. Ceremonial rides such as Princess Crown Carriage and Wedding Bicycle Ride suit couple or event entrances. Creatures such as Golden Phoenix Rise and Frost Spirit Wolf feel rarer and fit the top tiers.

Every entrance in the collection is sold on its own. If you want a set to map across your tiers, the Entry Effects Pack bundles 13 entrances for less than buying them one by one, and the VIP Arrivals Pack adds rockets, winged banners and entrances for VIP joins: 15 files.

Next step

Pick two entrances, one short and one long, and drop them into the free SVGA & PAG viewer to check their size, frame rate and how they sit on different room backgrounds. Then write down your queue rules before writing any code: those rules shape how arrivals feel far more than any single animation.
