=========================================================================
|
|
This is the code for Moving Light Entities (Dynamic Lights)
|
|
It's basically identical to the the func_train code with out
|
|
stuff like damage and blocked code used for solid objects.
|
|
The light follows Targets and waits just like a train.
|
|
A new variable (dynlight_style) defines the type of light emitted.
|
|
Quake has only three dynamic light styles:
|
|
1 - Dimlight
|
|
2 - Brightlight
|
|
3 - Brightfield (Brightlight with 'shimmering' particles)
|
|
Dynamic Light can also be triggered, They currenty only start turned off.
