DYNAMIC
Tells wether an entity is dynamic, i.e. it can change its position or parameters at runtime, can trigger or execute events, and is affected by game_save / game_load. If this flag is not set, the entity is static, meaning that it doesn't change at runtime. Static entities consume less memory and CPU resources than dynamic entities.
Type:
flag (emask)
Remarks:

* Entities placed in a level are dynamic if an action is assigned; otherwise they are static. Therefore do not assign unnecessary actions to entities.
* Entities created by ent_create are always dynamic.
* Static entites won't run events, including material events. Their parameters, except for their skills, can't be changed. They are not updated to the clients in a multiplayer system and are not saved by game_save.
* If an entity does not change anymore, this flag can be reset on a single player system for improving the frame rate.
* Static entities won't get environment light updates when their position changes. So when displacing a static entity, switch it's dynamic flag on for one frame in order for it's lighting to be updated to its new position.

Example:

action make_me_static()
{
// set up the entity
...
my.DYNAMIC = OFF; //C-Script
my.emask &= ~DYNAMIC; //lite-C
}
