¶ Overview
Sight components are an integral part of any sight, whether internal or attachable. Attachable sights are of class GBDirectSight, but will include a GBSightComponent blueprint component.
You may want or need to have internal sights, and these also use the GBSightComponent blueprint component. A lot of the standard sight properties will be irrelevant (for example relating to magnification).
¶ Properties of GBSightComponent
The most useful/pertinent properties of the sight blueprint component are listed below:
Figure 1. Properties of GBSightComponent
-
Sight TypePossible sight types are:-
Fail SafeFolded down and not in normal use. Essentially a cosmetic item in Ground Branch. -
Iron SightA mesh providing a sight picture in conjunction with a front sight post. Usually inbuilt. -
Red DotA non-magnified projection-based/holographic sight -
OpticalA simulated optical sight (implemented using scene captures). -
Post ModifierAn optical or other device placed in front of a sight to modify the sight picture. For example, the AN-PVS22 night vision sight. -
Pre ModifierAn optical or other device placed behind a sight to modify the sight picture. For example, the G33 magnifier.
-
-
Default Zero DistanceThe default zero distance in metres -
Optic RadiusIf you don’t know what this is, you probably don’t need to use it -
Min OffsetThe minimum amount the sight can be offset for zeroing -
Max OffsetThe maximum amount the sight can be offset for zeroing -
Min Magnification LevelThe minimum magnification (for adjustable optical sights) -
Max Magnification LevelThe maximum magnification (for adjustable optical sights) -
Default Magnification LevelThe default magnification (1.0 for iron sights, and so on) -
Stat KeyCurrently unused -
Material IndexSeeFirst Person Materialbelow. -
First Person MaterialHigher quality material to use when directly focused on this sight in first person mode. If valid, the game will use this in place of the normal material on the mesh atMaterial Indexmaterial index. -
Reticle Brightness NameThe name of the scalar parameter in the reticle material which controls the reticle brightness in the material. -
Reticle Brightness ScaleThe value to multiply the reticle brightness by when setting theReticle Brightness Namescalar parameter
¶ Zeroing a sight
When a sight is applied to a weapon, it will be automatically zeroed using the properties specified above. An adjustment will be calculated to the front sight post in order to achieve the desired zeroing, and this will be passed on to the weapon to implement via the animation blueprint.
See the latter examples in weapon blueprint code examples.
