Okay, I've managed to implement everything I've planned and also created a smaller moving-"tool". Unfortunate I couldn't create a smooth transition before the sparkles are visible, because there is a itsy-bitsy-tiny visibility-delay I can't get rid of.

But here is what I have for you (you can also see it in the video).
Flashlight:

• Finds objects of interest and hidden items (you can't find the hidden items without flashlight. Therefore these items are optional)

• A transition of the light if you change facing (not very well visible in the video, because of frame-loss)

• The crosshairs are now transparent sparkles

• Battery: Drains itself after a while

• Battery will drain itself even faster if you switch it ON and OFF in a short period of time (I don't want "energy-cheating"). There more you wait there less is the "punishment". And after 3 seconds there is no loss at all. The battery will flash red (stronger or weaker) to give the player an indication of his action. I will not explain this to the player with words

• With 1 bar left, the flashlight will shorten it's detection range (the graphic of this isn't finished)

Other stuff:

• If you hold Shift, you can lock your position and change your facing

And this was it for today!
