Function Documentation

get_const_var() [1/2]

template<typename T >

T get_const_var	(	const char *	name,
		const T &	default_value = {} ) const

Get the value of an exported script variable.

This operation will panic if no const var with the provided name was found, or if the type of the variable cannot be converted to the provided type.

An exported variable can be created in a script like this:

export const x = f64: 10

See the Flecs script manual for more details.

Template Parameters

T	The type of the value to obtain.

Parameters

name	The name of the exported variable.
default_value	Optional default value. Returned when const var lookup failed.

Returns

The value of the variable.

get_const_var() [2/2]

template<typename T >

void get_const_var	(	const char *	name,
		T &	out,
		const T &	default_value = {} ) const

Get the value of an exported script variable.

This operation will panic if no const var with the provided name was found, or if the type of the variable cannot be converted to the provided type.

An exported variable can be created in a script like this:

export const x = f64: 10

See the Flecs script manual for more details.

Template Parameters

T	The type of the value to obtain.

Parameters

name	The name of the exported variable.
out	Optional pointer to out variable. Can be used to automatically deduce T.
default_value	Optional default value. Returned when const var lookup failed.
