无缝交互

[halogp]

这个引擎是支持无缝地图的，那在逻辑代码里面，一个玩家可以直接修改另一个玩家的数据吗，比如给周围的一个人加buff。
因为另一个人可能是一个ghost，那数据的修改会不会被real同步过来的数据给覆盖掉。

对于ghost那是可能覆盖的

[halogp]

像这种一个物件修改另一个物件的属性或者方法，需要什么规则来保证开发流程正确吗，因为另一个物件很有可能是ghost。

ghost的属性是只读的，所以你改不了，你只能通过他的real去改，也就不会有你说的被real覆盖掉的问题了

Ghost properties can be changed by calling a remote method through another component (CellViaBase). For example, there is an entity entity1 in Python code on Cellapp and entity1 is a ghost. You can change a property of a real entity by calling a remote method on that entity's ghost. The method will be called on a real entity, in which you can already change the property value.

entity1.base.cell.change_my_property('new_value')

base.cell is CellViaBase, a call to a remote cell method via the base component. Baseapp knows where the real entity is and calls the method on the real entity. Through a method you can change a property of a real entity.

In entity_defs you need to add a change_my_property method to the entity1 entity class. This method should not be <Exposed/>.

Here is an example based on the demo, where I call the cell method of the Avatar entity through the base component. I added a change_my_property method to the avatar in the Avatar.def file and implemented the method in cell/Avatar.py
