Why can't I update the score value?

newbiSoso

I have the score defined as below to be printed on screen

 property int score_int : 0
Text{
    id: score
    text: score_int
    color: "white"
    anchors.verticalCenter: timer.verticalCenter
    anchors.horizontalCenter: attributes.horizontalCenter
    font.pixelSize: timer.height
    font.family: gill.name
 }

and here are two shapes "plus" and "minus" where their colors change:

Text{
                id: plus
                text: "+"
                color: "#ff4140"
                font.family: gill.name
                anchors.top: indicator.bottom
                anchors.topMargin: -(attributes.height-indicator.height)*0.4
                anchors.left: attributes.left
                anchors.leftMargin: attributes.width/6
                font.pixelSize: (attributes.height-indicator.height)*1.5
            }
            Text{
                id: minus
                text: "|"
                rotation: 90
                color: "#ff4140"
                font.family: gill.name
                y: Math.ceil((attributes.height-indicator.height)/2)
                anchors.verticalCenter: plus.verticalCenter
                anchors.right: attributes.right
                anchors.rightMargin: attributes.width/6
                font.pixelSize: plus.font.pixelSize*0.5
                font.bold: true
            }

and this list model to access and change square colors and text values in a grid

property variant colorArray: ["#008499","#963A65","#01FF97","#FF4140"]

        id: dummyModel

            dummyModel.setProperty(i,"squareColor",colorArray[Math.floor(Math.random()*3)])

Timer { 
    // to change score values in grid element randomly
    id: beta
    interval: 2000; running: true; repeat: true
    onTriggered: {
        for (var i=0;i<dummyModel.count;i++) {
            var sc = Math.floor(Math.random()*20) // random value from 0 to 20
            dummyModel.setProperty(i,"txt",sc) // score in each square
        }
    }
}

and this grid contains colored squares, when a square is clicked and color is the same as plus the number should be added to the score:

                Repeater{

                                    score_int = score_int + model.txt

                                    model.squareColor = "transparent"
                                }
                                else if (model.squareColor === minus.color){
                                    score_int = score_int - model.txt
                                    //time.value+=100
                                    model.squareColor = "transparent"
                                }
                                else if (model.squareColor === "black"){
                                    score_int = 0
                                }
                            }
                        }
                    }
                }
            }

but score can't be updated and there seems no syntax errors, why is that?

ODБOï

hi,
it's hard to say with little code snippets like this,

@newbisoso said in Why can't I update the score value?:

but score can't be updated and there seems no syntax errors, why is that?

score_int = score_int - model.txt
// console.log(model.txt) ;  console.log(typeof(model.txt))

have you checked the value and type of model.txt here ?

newbiSoso

Yes I did.
If I have the console.log statement directly after the "score_int = " statement it prints nothing to the console, unlike when I have it below the last if statement I get the value of model.txt and NUMBER :

score_int = score_int - model.txt
console.log(model.txt) ;  console.log(typeof(model.txt))   //prints nothing
.......
else if (model.squareColor === "black"){
                                    score_int = 0
                                }
console.log(model.txt) ;  console.log(typeof(model.txt))   //prints output to the screen

Hi @newbiSoso , just use "==" instead of "==="

Code:-

 if (squareColor == plus.color){
                                         score_int = score_int + txt
                                         //time.value -=100
                                         squareColor = "transparent"
                                     }
                                     else if (squareColor == minus.color){
                                         score_int = score_int - txt
                                         //time.value+=100
                                         squareColor = "transparent"
                                     }
                                     else if (squareColor == "black"){
                                         score_int = 0
                                     }
