Everything is in $3$d.
Assuming the player speed is $375$ units/second, and the missile being casted travels at $2000$ units/second with an initial cast delay of $0.25$s and width of $150$ units, the player can easily change direction (or simply stop moving) to evade the missile. I'm solving the interception point using the quadratic equation method.
The missile can be cast only once every $30$ seconds for example, so it hitting is highly preferred and the range of it is capped at eg $1200$ units.
The missile can not change directions and is a straight line.
How would I go about creating a somewhat accurate hit probability formula that generates a value between $0.0$ and $1.0$, assuming I have the interception point, last path change time, average time in which the player changes path etc?
I'm totally lost.
