Type

Description

boolReturns true if component 
T
exists on 
entity
, or false if it does not.

Remarks

If 
T
is a zero-size component, 
outRef
will not contain a valid reference; zero-size components do not have an address in memory. However, this function will still return true or false depending on whether 
entity
has component 
T
.
