There are x stats related to vision, that determine whether you can see a certain tile or actor:
- Vision Range
- Light Radius
- See stealth
- See invisibility
Also, terrain may have 3 different states that will affect what you may or may not see.
A tile may be:
- Lit: These tiles are lit by the sun, or through magically field, and do not hinder your sight.
- Unlit: You may not see these tiles unless your lite reaches to it (determined by your light radius).
- Covered in magical darkness: Blocks all vision and light, can be only lit up with Sun Infusion and certain artifacts.
Similarly, there are several stats that help you hide from your enemies:
(more info needed)
This is how far you can see. You shouldn't be able to see anything further away than this. For most actors, this has a value of 10.
How far your light reaches. You can see unlit tiles only if they are within this radius. Currently overrides vision range and allows you to achieve effective vision radius above 10.
Allows you to see creatures in darkness within a certain radius. Effectively lights up tiles with creatures on them, showing items and effects too. Doesn't stack with Heightened senses Needs verification, despite having identical effects. However Infravision does not light up tiles themselves eg. walls, trees.
Allows you to perceive certain kinds of creatures with your mind. Diggable walls, doors, blindness, invisibility or magical darkness don't affect telepathy.
