  • [Confirmed] Gyrocopter's Homing Missile deals too less damage

    In Dota 2 Homing Missile has to travel more than in DotA 1 to deal the same damage.

    Reproduction: Cast Homing Missile from maximum cast range (~945 units between the missile and the target) and stand still with the target to prevent accidental movement.

    As the level 4 Missile strikes it deals ~197 damage
    In DotA 1 the Missile deals ~237 damage within the same distance traveled.

    Travel Distance to deal full damage
    DotA 1
    Dota 2

    there might be a slight difference with the Homing Missile impact distance. D1 46 units apart from the target. D2 34 units. Could be caused by low refreshing rate for the values within the test map.

    how do you get warcraft 3 to show all that stuff?

            In dota 1 distance from which damage is calculated is from gyro center.

            As you can see damage formula at level 4 will be 50<440*(distance traveled<1500)/1500

            Distance error can be up to 20

            Firing rocket from 1000 range

            The damage is 216.5. Lets check if it does not contradict our formula. 216.5:0.75=288.7 | 288.7/440*1500=984.2 Which fits our distance error.

            In dota 2 however damage distance is calculated from initial missile position:


            Axe and Gyro is 1000 distance away

            As you can see the damage is 177. Lets calculate the distance such damage should be dealt from: 177:0.75=236|236/440*1500=804

            The distance that rocket traveled from its initial position is 950-150=800 thus Homing missile calculates distance from rockets initial position
