Why not get a vector of the distance between the player and the bomb:

SAAB - all that chwilly's code does is to give you the distance between the player and the bomb.

You need to work out the damage from that.

A reasonable formula for damge by distance might be something like:
Damage = 100/(Dist+1)
This would do 100 damage at Dist = 0, (I use Dist + 1 to get rid of the problem of dividing by zero), then do 50 damage at one unit distance, then 33.3 at 2 units and so on down to ~9 damage at 10.

If you want a wider radius for the explosion, you could do something like:
Damage=100/((Dist/10)+1)
which would reduce much slower.

I like SAAD's idea for damage based on distance.

The code is just the Pythagerean theorom:

a^2 + b^2 = c^2 (c = the distance between the player and the bomb)

so c = sqrt(a^2 + b^2)

I don't know if DB has a native command to get that thought.
