Hi all!
I'm making a compass addon with a POI feature that makes little dots which mark the directions to the corresponding POI's. When that dot is in the center of your screen your facing the POI directly, and when you turn a bit to the right the dot moves to the left(which is logical, if you are facing a house in WoW and turn to the right the house moves to the left) of the screen. What I want is when the POI goes off-screen thanks to the FOV I want the dot also go off-screen. Now to do this I need to know the FOV of WoW, hence my question.
Some extra info:
I know the distance to the POI in yards.
I know the angle "that would be needed to turn to the right to correctly face the POI", example: a house is in front of you and you turn 90 degrees to the right the angle is -90.
The angle goes from -180 to 180 where 0 is perfectly facing the POI.
I place the dots on the screen like this, which assumes a FOV of 180 degrees:
Code:
dot:SetPoint("TOP", UIParent, dot.angle/90 * -GetScreenWidth(), 0)
I hope you guys can help me!
