This post is part of a series in learning how to make games with PuzzleScript. If you haven’t read my previous tutorials, I recommend you do so here, as that is assumed knowledge for this post.

Specifying Directions

There might be times when you want to check if an object is moving in a certain direction. I experimented a bit with this in Puzzledorf, but it didn’t suit my puzzles. If you have a unique idea to try it with though, this is how you do it.

Open up PuzzleScript, make a new game based on the Basic example and replace their Rules with the following code:

[ Left Player ] -> [ Crate ]

Run the game and see what happens.

If you try and walk left at any point, the player will turn into a crate. This is a really good example of how specifying directions works.

We’re used to this format I’ve used before to explain code in PuzzleScript:

[ Condition ] -> [ Event ]

If the condition is true, the event will occur.

But now that we want to check for directions, it follows new rules:

[ Movement Direction Object Affected ] -> [ New State of Object ]

So our previous code:

[ Left Player ] -> [ Crate ]

Is checking if the player is moving Left. If it is, swap the player with the crate object.

Direction Types

The different types of directions you can choose from are:

• Up
• Down
• Left
• Right
• Horizontal (checks to see if there is any horizontal movement)
• Vertical (checks to see if there is any vertical movement)

Conclusion

The next tutorial is on how to create custom movements.
