Note: the operation is not commutative, which means that changing the order of the Rotations does change the result.

Here's a script to get you started.

Explaination of the above script: Rot A is the rotation of the block. Use get position if you made the block to have other rotations too (You have to get the rotation in a single frame, or else it will become a loop of the LERP script trying to set it back to Rot B.). Rot B is the rotation you want the block to go to. Set B to the rotation you want. "Speed" is the speed of changing the rotation A to rotation B.

Now it will be easier to understand LERP, with which you can do smooth rotations.

To change the value of the number block, select the block, then tap the button right below the open inventory button, in the bottom right corner.

This will open up the keypad, which you can use to change the value that the number script block will output.

1. Set the light angle to the same as the camera angle.

2. Set Camera with a very high Y.

They can be changed by selecting the touch sensor and tapping the buttons that appear in the bottom right corner.

The first button has three options:

When you tap Play, script blocks *execute* and do their thing. E.g. [[Set Score]] sets the current score, so if we wire the [[Number]] 3 to it, the score is set to 3.

There are other wire colors as well:

LERP is a very good script for changing Rot A which is the rotation of a block to Rot B, smoothly.

There are several ways to achieve it. The first one is changing camera rotation depending on the screen orientation so the way a player flips a device doesn't have an effect on what is displayed on screen:

These scripts will set vertical orientation. If you want horizontal, just wire that [[Set Rotation|Set Variable]] to the "Else" plug instead of "True".

The second method is way straightforward, just place the [[Accelerometer]] script block anywhere on floor (don't forget to wire it to something with yellow plugs!) — it will literally lock the screen orientation to a state that was when a game was opened. It's useful when you don't necessarily need a specific orientation to be set but you want it to be unchangeable during gameplay.

Might be worth noting that all of these are a last resort for games that are not just inconvenient, but impossible, to play in the "other" orientation. Else just let the user play the way they prefer.

There are multiple ways to make a loop one of the ways to make one is to make a repeating timer by make so that every frame num is increased by 1 and then when num=120 (60 frames is 1 sec) a sound plays.

Assuming you're making a top-down view game, zoom = 5 * block width. E.g. to fit 10 blocks wide, set zoom to 50:

What about height? Well, different users will have different screen sizes, so even with a fixed width the height is variable. But like the image shows, you can compute it by multiplying width by the screen's aspect ratio.

Zoom automatically adapts to the smallest dimension, so in landscape mode the role of height and width are reversed.
