| If MF_NEW_LEG is not set, then do nothing at all | |
| If MF_TURN is not set, then just walk one step | |
| If MF_TURN is set | |
| we have reached a walk target (may not be the users requested destination) | |
| If MF_IN_LEG is set, we have reached our final destination/target. Stop Actor Moving completely | |
| If MF_IN_NOT is not set, we have reached the current target | |
| Check the walk box number, is it the final destination walk box | |
| Yes: Set the next walk destination to the X/Y the user clicked, set MF_IN_LEG… do calcMovementFactor | |
| No: Get the next walkbox, check its flags, calculate the point we should walk to inside this box (towards the final destination), do calcMovementFactor | |
| calcMovementFactor disables MF_TURN, | |
| calculates the walk distance / direction, calls walk step. | |
| Unless walk distance is 0, in which case it sets MF_TURN and does nothing else | |
| Walkstep: increases or decreases the X and Y value depending on which direction we are walking (it will do both, IF your walking on enough of an angle) | |
| Sets MF_TURN once the current destination has been reached |
