Nightvision

Two styles of NVG

Featureful SDK implements two styles of Night vision goggles:

• Classic Opposing Force night vision (requires sprites/of_nv_b.spr resource in the mod directory).
• Counter Strike like night vision.

The Counter Strike style is usually better accepted by players, so it's the default option in Featureful SDK.

Enabling and configuring NVG

In order to let player have NVG instead of the flashlight set suit_light feature in featureful_server.cfg to nvg. You should also configure the nvg_sound_on and nvg_sound_off features - they must refer to sounds.

In featureful_client.cfg you can configure the NVG parameters (like color, brightness) and whether the NVG style can be chosen by player with the help of the cl_nvgstyle cvar. Opposing Force and Counter Strike NVG parameters are configured separately.

Allowing both flashlight and NVG

You can allow player to hold both flashlight and NVG. To do so set suit_light_allow_both feature in featureful_server.cfg to true. The player can obtain the flashlight by picking up item_flashlight and NVG by picking up item_nvgs. The default light item coming with a suit depends on the suit_light feature.

If player has both items, then the flashlight command (impulse 100) toggles the flashlight. To use the NVG in this case player should bind nightvision command. To let player configure this keybind via menu, the mod developer needs to add a new line somewhere in gfx/shell/kb_act.lst:

"nightvision" "Nightvision"

Note that flashlight and NVG share the same battery and currently there's no option to configure this behavior.

NVG icon sprites

Your mod might feature the flashlight in one part of the campaign and the NVG in another part. In this case you want different sprites to show up depending on the current light item.

nvg_empty_sprite and nvg_full_sprite features in featureful_client.cfg allow to configure which sprite names from hud.txt should be used when player has NVG.
