Is it possible to create mods?

Arrows can be used as direction indicators (for movement or to point to a specific object. Or: red – danger, green – safe passage; in general, use them however your imagination suggests). As I mentioned before, the mod allows you to display the values of numerical variables in text (I provided an example). This means you no longer need to write long scripts like: if variable "A" = 1, then display the text "one, one, one" if variable "A" = 2, then display the text "two, two, two" and so on. Moreover, the mod allows you to create conditional statements in the text. Here's a simple example: ?(PUZZLE_Temple5=1 : `Red` | PUZZLE_Temple5=2 : `Orange` | PUZZLE_Temple5=3 : `Yellow` | PUZZLE_Temple5=4 : `Green` | PUZZLE_Temple5=5 : `Blue` | PUZZLE_Temple5=6 : `Indigo` | PUZZLE_Temple5=7 : `Violet`) sea wave symbol. Accordingly, depending on the value of the PUZZLE_Temple5 variable, the following will be displayed on the screen: " sea wave symbol". The syntax is copied exactly: the text for each value of the variable is enclosed in backticks; the presence of spaces between the : and | symbols does not seem to matter
