Что нужно сделать, чтобы устроить пожар:
1. На те объекты, которым позволительно гореть, надо повесить скрипт FireController. У него есть несколько свойств:
а) Is Combustible (boolean) ― может ли объект загораться,
б) Is Burning (boolean) ― горит ли объект в данный момент,
в) Intensity (int) ― интенсивность горения (пока это просто количество частиц огня; чем больше объект, тем большее желательно значение).
2. Добавить любой коллайдер к объектам, которые должны уметь загораться от горящих соседей.
3. Поместить на сцену экземпляр префаба FireManager. У него есть два свойства:
а) Burning Dummy Prefab ― болванка с настроенной системой частиц для показа пламени.
б) Sparking Dummy Prefab ― болванка с настроенной системой частиц для разлетающихся угольков.
Как работает:
1. При старте FireManager находит все объекты с подключенным FireController и поджигает те, у которых IsBurning = true.
2. Когда объект зажигается, в его позиции в пространстве создаются невидимые экземпляры источников частиц пламени и угольков. В них используется MeshParticleEmitter, у которого свойство mesh подменяется сеткой реального поджигаемого объекта. В результате частицы появляются по всей поверхности объекта.
3. Если разлетающиеся в разные стороны угольки попадают на соседний объект, у которого есть какой-нибудь коллайдер, подключен скрипт FireController и в нем IsCombustible = true, то этот соседний объект точно так же загорается.
4. Чтобы поджечь объект вручную, у него нужно вызвать функцию Ignite(). Чтобы погасить горящий объект ― функцию Extinguish().
