A new version (1.0.4) will soon™ release, featuring (TLDR) ; changes to the manual blink (C), a new experimental and optional feature and changes to the config.
After more than a week, I can conclude that my potential fix (added in 1.0.3) to prevent blinking while spectating works. It took so long 'cause me and my friends weren't playing the game, and while I can play solo, I cannot spectate nothing, so I couldn't confirm anything.
Anyway, small changelog (the thunderstore changelog will be complete):
• Blink duration and interval were slightly increased to match SCP:CB's. (still random)
• Manually blinking (C) now sets your next blink interval to 14s, and no longer grants a delay to blink interval.
• Keeping your eyes shut now slowly decreases your insanity, which in turn makes blinking less frequent.
• You can now edit both fade-in and fade-out ratio of a blink duration (eyes closed to open, etc.)
• Hypothetical fix to a case where blinking when dying would make your spectating screen go permanently dark (until respawn). Hypothetical as this only ever happened (to me) on this new version, BUT, it may have of happened before.
• Experimental : Blink on 'fear events'. Disabled by default.
○ Whenever you'd gain a sudden surge of fear based on certain events, you will blink.
○ Some of these events are : Thumper's screech, seeing the Bracken, being too close to a creature, getting hit, seeing a body, etc.
This is not a mandatory update; blinking, the main feature of the mod still does what it should, if you don't want/need anything else, you won't need to update.
