One Sprite One Script Project
Below are some of the many methods used to avoid extra scripts or sprites:
- Multiple sprite movement — The sprite will place itself at a certain set of coordinates, stamp itself, and move away, doing this at another place in an another costume to give the illusion of many sprites.
- Swift "Auto-Lines" — To draw a quick line between two points use this script:
when gf clicked clear pen up go to x: (0) y: (0)//starting position pen down go to x: (100) y: (100)//end position pen up
- Single Frame — This method is used to speed up scripts.
HistoryScratch Team that 1s1s projects are becoming a big trend. However, since the release of Scratch 2.0, their popularity has dramatically decreased. Although many 1s1s projects have been made before, some say that RHY3756547's LINE was the first major 1 Sprite 1 Script project — this project most likely triggered the fad. Following this project, many people made their own 1s1s projects, from games to simulations. There was also a Scratch Design Studio with 1s1s projects.

- The Wait () Secs block will slow the entire script - one solution is to have the sprite change a variable repeatedly until it has reached a certain value. This can be an advantage or disadvantage, depending on the situation — it will be measured by the amount of frames, not the amount of time. Another solution to this is to reset the timer, and have the sprite repeat its normal functions until the timer is greater than or equal to the wanted time. The best solution is to make the script Single Frame.
- A script has a limited area to show itself — once the script is long enough, it will cut its view at that point and below. The Scratch Team has noticed this problem; it will probably be fixed in the next version of Scratch, Scratch 2.0.

Zero Sprite One Script (0s1s)
Some tricks for programming in this way are as follows:
- Multiple object movement—The Stage is frozen; it cannot place itself at different locations and stamp. Some backgrounds form an animation, resembling the wanted effect - but it is rather glitchy.
- Mouse detection—The stage can switch to a new background by looking at a mouse's coordinates. Using these, it can check to see if the mouse is in a certain region on the screen.
Mainly, 0s1s projects are math simulations, chatbots, console OS's, etc., mainly which do not need graphics. Main interactivity is usually by using the Ask block for input and a List display for output.
One Sprite One Script One Costume (1s1s1c)
Other users, finding One Sprite One Script projects too easy and Zero Sprite One Script projects too hard, settle for One Sprite One Script One Costume projects. With only one costume but one sprite, there are limitations to what the project can stamp, so these projects use the Pen to draw objects. This is slow and time-consuming to program, so these projects are also difficult to make.
