How to do explosion damage to enemy with multiple collider?
I make a tank game that the tank has multiple collider s in turret and multiple colliders in hull as the armor. When it take a damage, the tank get multiple damage because it has multiple colliders.
I was using overlap sphere to damage multiple enemies but i just wanna make a damage per enemy in explosion radius not multiple damage for multiple enemies in explosion radius.
So, how to do damage to enemies with multiple collider in it?
How do you send damage data to other tanks? You should create a class object and assign it to enemy tanks (but I guess there is already), then when the bullet hits something you could make a map with Closest point per Enemy:
Dictionary<Enemy, float> distanceToTanks = new Dictionary<Enemy, float>();
Then, everytime a collider is hit, you look for Enemy's script and you set the distance only if it's less then the current value:
float currentDistance = Vector3.Distance(middle, collider.ClosestPoint(middle));
Enemy enemy = ...
if (!distanceToTanks.ContainsKey(enemy) || currentDistance < distanceToTanks[enemy]){
distanceToTanks[enemy] = currentDistance;
}
At the end you can iterate through the dictionary to apply damage:
foreach (KeyValuePair<Enemy, float> values in distanceToTanks) {
enemy.ApplyDamage(values.Value, ...);
}
Is this also work when the colliders is separate child?
Yes, of course, as long as the class that represents the tank (which I called Enemy) is the same. You could place that component on the root, the other colliders on first level children and do something like this: Enemy enemy = transform.parent.GetComponent();
