Snap! Blocks

Перечень всех блоков Snap! доступных в версии 8.0 - их можно использовать при описании процедур в вики, объединяя между собой

Blocks

Motion

move (10) steps: Moves the sprite along their direction.

turn cw (15) degrees: Turns the sprite clockwise.

turn ccw (15) degrees: Turns the sprite counter-clockwise.

point in direction (90 v): Points the sprite towards a direction. 90 is right, 0 is up. Use "random" to point towards a random direction.

point towards [mouse-pointer V]: Points the sprite towards another sprite. The block can also be used to make a sprite face toward a mouse pointer or the center.

go to x: (0) y: (0): Jumps the sprite to a position.

go to [random position V]: Jumps the sprite to another sprite, the mouse pointer, or the center. A two-input list can be also dropped into the slot for a select position.

glide (1) secs to x: (0) y: (0): Smoothly (linearly) moves the sprite to a position.

change x by (10): Moves the sprite horizontally. Positive to move right, positive to move left.

set x to (0): Changes the sprite's horizontal position.

change y by (10): Moves the sprite vertically. Positive to move up, negative to move down.

set y to (0): Changes the sprite's vertical position.

if on edge, bounce: Makes the sprite face away from the edge if it's in proximity, otherwise does nothing.

(position): Reports the sprite's current position as a two-item list.

(x position): Reports the current horizontal position.

(y position): Reports the current vertical position.

(direction): Reports the sprite's direction.

Looks

switch to costume [ V]: Changes the sprite's costume.

next costume: Cycles the sprite's costume to the next one. The turtle costume is never rolled over using this block.

(costume #): Reports the current costume number. 0 is the turtle costume, and other costumes start from 1 onwards.

say [Hello!] for (2) secs: Shows a speech bubble above a sprite for an amount of time. If run on the stage, a pop-up will appear on the top-left.

say [Hello!]: Shows a speech bubble without pausing the execution.

think [Hmm...] for (2) secs: Like the say blocks, but shows a thought bubble for an amount of time. Conversely, it cannot be run on the stage.

think [Hmm...]: Shows a thought bubble without pausing the execution.

([width V] of costume [current V]): Reports a property of the costume.

(stretch [current V] x: (100) y: (50) %): Stretches a costume.

(new costume @list width ( v) height ( v)): Creates a costume from a list.

change [ghost V] effect by (25): Intensifies or lessens an effect.

set [ghost V] effect to (0): Sets an effect intensity.

clear graphic effects: Resets all the effect amounts to 0.

([ghost V] effect): Reports the current amount of an effect.

change size by (10): Grows or shrinks the sprite. Note that it's not applied by a factor, 1.5 does not set the size to 150% from 100%, it sets it to 101.5%.

set size to (100) %: Sets the size of the sprite.

(size): Reports the current size.

show: Reveals the sprite if the sprite is currently hidden.

hide: Hides the sprite and ceases all touch sensing (other sprites cannot sense if they're touching hidden sprites, and "when I am clicked" events are disabled as well).

<shown?>: Reports true if the sprite is shown, false otherwise.

go to [front V] layer: Sends the sprite to either the front or back layer. Sending a sprite to front will also put it in front of UI elements, such as variable watchers, speech bubbles and ask dialogs.

go back (1) layers: Send the sprite backwards by an amount of layers.

Sound

play sound [ V]: Plays a sound with its own sample rate.

play sound [ V] until done: Plays a sound and waits until the sound is done.

stop all sounds: Stops all the sounds that are currently being played.

play sound [ V] at (44100 v) Hz: Plays a sound with a set sample rate.

([duration V] of sound [ V]): Reports a property of a sound.

(new sound @list rate (44100 v) Hz): Creates a sound from the samples given.

rest for (0.2) beats: Delays execution for a varying amount of time based on the tempo.

play note (60 v) for (0.5) beats: Plays a note.

set instrument to (1 v): Sets the instrument to be played into one of the four waveforms: (1) sine, (2) square, (3) sawtooth, (4) triangle. The triangle is not to be confused with a percussion instrument of the same name.
