The force of DuctFans/Tornadoes are set in datablock fields, rather than in object fields.
What that means is, where you see
Code:
datablock = "DuctFan";
You can change that to
Code:
datablock = "SmallDuctFan";
and it will use the SmallDuctFan datablock (which has reduced power). You can create a less powerful datablock by using this code at the
top of your mission file:
Code:
datablock StaticShapeData(WeakTornado : Tornado)
{
// Pull the marble in
forceType[0] = Spherical; // Force type {Spherical, Field, Cone}
forceStrength[0] = -60; // Force to apply
forceRadius[0] = 8; // Max radius
// Counter sphere to slow the marble down near the center
forceType[1] = Spherical;
forceStrength[1] = 60;
forceRadius[1] = 3;
// Field to shoot the marble up
forceType[2] = Field;
forceVector[2] = "0 0 1";
forceStrength[2] = 250;
forceRadius[2] = 3;
};
From there, you can change all the force values to better fit your tornado strength (those are the defaults). After that, simply change your tornado's datablock field from
Code:
datablock = "Tornado";
To
Code:
datablock = "WeakTornado";
Let me know if this works, or if you have any questions
