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