My solution:

Code: (Select All)

void OnStart()
{
    //Attach some prop detectors to the bridges
    AddAttachedPropToProp("bridge_1","collider_1","bridgeCollider.ent",0,0,0,0,0,0);
    AddAttachedPropToProp("bridge_2","collider_2","bridgeCollider.ent",0,0,0,0,0,0);
    
    //Callbacks
    AddEntityCollideCallback("barrel01_*","collider_1","cbAddPropBridgeDown",false,0);
    AddEntityCollideCallback("Player","collider_1","cbAddPropBridgeDown",false,0);
    AddEntityCollideCallback("barrel01_*","collider_2","cbAddPropBridgeUp",false,0);
    AddEntityCollideCallback("Player","collider_2","cbAddPropBridgeUp",false,0);
    
}


//Add/Remove a prop to the bridge we need to pull down
void cbAddPropBridgeDown(string &in asParent, string &in asChild, int alState)
{    
    if(asParent == "Player")
        AddLocalVarInt("BridgeDown",3 * alState); //Player ways 3x more than a barrel...
    else
        AddLocalVarInt("BridgeDown",alState);
    moveBridges();
}

//Add/Remove a prop to the bridge we need to pull up
void cbAddPropBridgeUp(string &in asParent, string &in asChild, int alState)
{
    
    if(asParent == "Player")
        AddLocalVarInt("BridgeUp",3 * alState); //Player ways 3x more than a barrel...
    else
        AddLocalVarInt("BridgeUp",alState);
    moveBridges();
}

//Determine what levels the bridges should move to
void moveBridges()
{
    //Relative weights on bridges
    int up   = GetLocalVarInt("BridgeUp");
    int down = GetLocalVarInt("BridgeDown");
    int diff = up - down;
    AddDebugMessage("Up: " + up + " Down: " + down + " Diff: " + diff,false);
    
    //Work out relative weights & clamp (to stop bridges going through the floor).
    float state = diff * 0.1f;
    if(state>1.0f)       state = 1.0f;
    else if(state<-0.5f) state = -0.5;
    
    //Move based on relative weights
    SetMoveObjectStateExt("bridge_1",-state,0.65f,1.5f,0.125f,true);
    SetMoveObjectStateExt("bridge_2",state,0.65f,1.5f,0.125f,true);
}

I used the Bridge Collider entity which i provided as an addition file.
