Ok, I fixed that. It was really just changing the funciton that determines the state which is a pretty easy one anyway.

Here is the solution:

And here goes the explaining:

PHP Code: (Select All)

const int MAX_BARRELS = 14;
const int playerWeight = 40;

float[] aBridge = {0, 0, 0};//USE VALUES BETWEEN 0 and 3.14/2(pi/2)!!!

//Note that the weight varies from 0 to 90 in the briges. This happens because the sen(x) function varies between MAX and MINIMUM values between 90 and -90 degrees or Pi/2 and -pi/2 radians.


void OnStart()
{
    AddAttachedPropToProp("bridge_1", "scriptCollider_Bridge_1", "bridgeCollider.ent", 0.0, 0.0, 0.0, 0.0, 0.0, 0.0); //Add the entity to detect if anything is ON the bridge.
    AddAttachedPropToProp("bridge_2", "scriptCollider_Bridge_2", "bridgeCollider.ent", 0.0, 0.0, 0.0, 0.0, 0.0, 0.0); 
    AddDebugMessage("Added Colliders",false);
    for(int i = 1; i<=MAX_BARRELS; i++)//For each barrel add a collide callback
    {
        AddEntityCollideCallback("scriptCollider_Bridge_1", "barrel01_"+i, "OnEntityCollide", false, 0 );
        AddEntityCollideCallback("scriptCollider_Bridge_2", "barrel01_"+i, "OnEntityCollide", false, 0 );
    }
    AddEntityCollideCallback("Player", "scriptCollider_Bridge_1", "OnEntityCollide", false, 0 ); //add collide callbacks for the player
    AddEntityCollideCallback("Player", "scriptCollider_Bridge_2", "OnEntityCollide", false, 0 );
    
}


void OnEntityCollide(string &in asParent, string &in asChild, int alState) 
{
    if(asParent == "scriptCollider_Bridge_1")
    {
        float fWeight = getWeight(asChild); //Function getweight returns the weight of a preset object.
        AddDebugMessage("Colided with bridge 1",false);
        if(alState == 1)//If is entering the area/Is now on the bridge
        {
            aBridge[1] += fWeight;//Increase bridge 1's weight
            aBridge[2] -= fWeight;//Bridge's 2 weight is reduced. This does not really happens. But since weight(force vector) + tension(assuming there is no friciton in the mechanism the tension equals the other bridges weight) equals a vector that equals: Bridge2weight-Bridge1weight. (without friction)
        }
        else if(alState == -1)//If is leaving the area/is now off the bridge
        {
            aBridge[1] -= fWeight; //Same, but now when an item exists the bridge.
            aBridge[2] += fWeight;
        }
        updateBridges();
        
    }
    else if(asParent == "scriptCollider_Bridge_2") //Same as above.
    {

I assume this makes me the winner.
