UE3 - UDK "ModfyProperty" variable arguments solution

[lorendroll]

I can't figure out how to increment object property via Kismet. I'm using ModifyProperty function but it doesn't allow to input variable property value (calculated somewhere else). I can only set it constant in property array string.

Partitialy solved by compiling inheritor of SeqAct_ModifyProperty:

class SeqAct_ModifyPropertyValue extends SeqAct_ModifyProperty;

var string Value;

event Activated()
{
	Properties[0].PropertyValue=Value;
}

defaultproperties
{
	ObjName="Modify Property Value"
	VariableLinks(1)=(ExpectedType=class'SeqVar_String',LinkDesc="Value",bWriteable=false,PropertyName=Value)
}

But this code doesn't work for the first time it fires, but works somehow for the second... Please help me find a better solution.

Also, I wrote a script specially for changing Drawing Scale of actor:

class SeqAct_ModifyDrawScale extends SequenceAction;

var string Value;
var object Target;

event Activated()
{
	Actor(Target).SetDrawScale( float(Value) );
}

static event int GetObjClassVersion()
{
	return Super.GetObjClassVersion() + 1;
}

defaultproperties
{
	ObjName="Modify DrawScale"
	ObjCategory="Object Property"
	VariableLinks(0)=(ExpectedType=class'SeqVar_Object',LinkDesc="Target",PropertyName=Target)
	VariableLinks(1)=(ExpectedType=class'SeqVar_String',LinkDesc="Value",bWriteable=false,PropertyName=Value)
}

But the only problem is collisions. Works properly with projectiles and player, but behave like non-modified when collides with static meshes or other rigid body... I tried using SetPhysicalCollisionProperties, SetCollisionType, SetCollisionSize, SetZone, SetCollision, SetPhysics functions... and no result. I looked at collision box (via console: show COLLISIONS) and everything was fine.
