Variables

A variable is a named storage for a value. This value can change over time through the operation called assignment. A variable can be assigned a literal (e.g. a number or a string) or a value of another variable. For example:

int hour = 12
int minute = 30

hour = 13
minute = 0

hour = minute

The first two lines declare two variables, hour and minute, and assign them values 12 and 30 respectively. The next two lines change the values of these variables to 13 and 0. Finally, the last line assigns the value of minute to hour. After this line, both hour and minute will have the value of 0.

Variables that hold integer values are declared with the int keyword. You can then use them in commands that expect an integer number. For example:

int hour = 12
int minute = 30

set_time_of_day hour minute

This script will set the time of day to 12:30.

Variables that hold floating-point values are declared with the float keyword. You can then use them in commands that expect a floating-point number. For example:

float timeScale = 0.5

set_time_scale timeScale

Variables that hold string values are declared with either string or longstring keywords. Again, we will discuss the difference between them later. You can then use string variables in commands that expect a string. For example:

string gxtKey = 'GXT_KEY'
longstring spriteName = "DOWN"

print_help gxtKey
load_sprite 1 spriteName
