|Switch Costume to ()|
This block is one of the most commonly used blocks; it is used whenever a sprite must switch to a specific costume (instead of the Next Costume block, which only switches to the next costume in the list). A variable (or any reporter) containing a number or the name of a costume can be dropped in.
In very early, unreleased beta versions of Scratch, this block was called Look Like (). This original name is also the reason why its Squeak method is called lookLike: for compatibility with projects made with older versions of Scratch.
Because of its simplicity, this block does not have a specific list of main uses — it is simply used to change the costume of a sprite. It can be used in animations, games, simulations, or anything that requires changes between costumes.
Some common uses are as follows:
- Simply changing a costume
when I receive [Broadcast v] switch costume to [costume2 v] go to x: (0) y: (0) show
- Changing a costume as part of a sequence
wait until <(variable) = > change x by (10) switch costume to [costume1 v]

This block can be replicated with the following code:
repeat until <(wanted costume #) = (costume #)> next costume end
However, it is normally much faster to use the original block.
Things Worth Noting
Naming Costume As a Number
When naming a costume as a number, users should note that scratch will be confused if you are trying to switch to the costume via
switch costume to (variable)
<(variable) = [integer]>
If possible, refrain from switching to a variable storing integer numbers, as scratch will get confused with the costume# and the actual name itself.
Effects of Too Many Layers on a Costume Switch
There is a glitch reported many times that sometimes a costume would not switch to the desired costume. This is usually the effect of the use of layers. Layers have a tendency to create immense lag, and therefore on less powerful computers/machines, this can cause a delay between switches in costume appearance.
