This module contain main templates for user.
|
|
There are three structure templates (mixins) which should be added on top of structure:
|
|
$(LIST
|
|
* System: make system structure
|
|
* Component: make component structure
|
|
* Event: make event structure
|
|
)
|
|
|

|
|
Struct System1
|
|
{
|
|
mixin!ECS.System;
|
|
}
|
|
|
|
Struct System2
|
|
{
|
|
mixin!ECS.System(16);//set number of jobs generated for system by multithreaded update
|
|
}
|
|
|
|
Struct Component1
|
|
{
|
|
mixin!ECS.Component;
|
|
}
|
|
|
|
Struct Event1
|
|
{
|
|
mixin!ECS.Event;
|
|
}
|
|
---
|
|
|
|
There is also template for generating list of excluded components "ExcludedComponets(T...)".
|
|
This template takes component structure types and making list of excluded components used in "registerSystem" function.
