Asserts that the [code]condition[/code] is [code]true[/code] . If the [code]condition[/code] is [code]false[/code], an error is generated and the program is halted until you resume it. Only executes in debug builds, or when running the game from the editor. Use it for debugging purposes, to make sure a statement is [code]true[/code] during development.

The optional [code]message[/code] argument, if given, is shown in addition to the generic "Assertion failed" message. You can use this to provide additional details about why the assertion failed.

# Imagine we always want speed to be between 0 and 20
speed = -10
assert(speed &lt; 20) # True, the program will continue
assert(speed &gt;= 0) # False, the program will stop
assert(speed &gt;= 0 &amp;&amp; speed &lt; 20) # You can also combine the two conditional statements in one check
assert(speed &lt; 20, "speed = %f, but the speed limit is 20" % speed) # Show a message with clarifying details
