Variables

From Wiki001

There are Tutorials related to Variables in the tutorial section of the 001 website. Click here to view them.

A variable is a placeholder symbol. It is used to store a value or text, that can be retrieved later anywhere in the game. Normally in programming you have to know and decide if the variable is a string, an integer, or a real, but thankfully Engine001 automatically allows variables to be any of these, and can be converted seamlessly.

It is quite common for a game to first use Variable Operation to alter a variable for different circumstances, and later use Comparison Branch to check if the variable is a certain number.

Global variables are located under the Scripting section on the left panel in Map001.

Uses

Variables are used in almost every script that makes a game good, including quests, banks, names, cheats, and almost any other script you can think of.

You can use a variable to find what the player types in an Input Box, or find what option he chose from a Message Box and save by using Variable Operation, so you can use it later in the game. Alternatively, you could just use a Switch.

See the tutorials and forum for guides on how to make the scripts mentioned above, and more.

Local Variables

Local variables are useful when you want a variable to be used in only one event script, and want it to reset to 0 after the script is finished. Example: A Poker game where the pot is reset after the game ends, without having to make a new event to set it back to 0.

Map Variables

Map variables are variables that are specific to a certain map. They can be created and altered from the Map Properties window, which can be accessed in the Map menu (next to file) or when you first create a map. These are usefull for events that only occur in the one map, but can be altered or retrieved anywhere.
