I have a text file with a string of texture names

"mycursor.png", "gcur.png", "gcur_action.png", "gcur_forward.png", "gcur_down.png"

this works:

const cursorNames =["mycursor.png", "gcur.png", "gcur_action.png", "gcur_forward.png", "gcur_down.png"];

and I know:

 curtxt =ccbReadFileContent( "cursor.txt").toString('utf-8');

reads the file, but how do I use the text file rather than string in the code line

I hope it makes sense :|

split will do the job for you.

var stringfromfile=ccbReadFileContent("MyFile.txt");

var lines = stringfromfile.split('\n');

for(var i = 0; i < lines.length; i++){
print( lines[i]);
}

instead of '\n' you can use whatever separator you want to use here.. for example "," or space.

here's what I've come up with, I wanted various types of cursors controlled by a variable, which changes depending on the hotspot interaction, I can also do inventory cursors
I might have a look at doing the switch code dynamically


/* <action jsname="action_addcursor" description="add cursor">
    <property name="Cursor_Path" type="string" default="cursors/" />
 </action>
*/
// 

action_addcursor = function () {

};
action_addcursor.prototype.execute = function (currentNode) {
    var path = this.Cursor_Path;
    print(path);
    const cursorNames = [];
    var stringfromfile = ccbReadFileContent("cursor.txt");
    var lines = stringfromfile.split(',');
    for (var i = 0; i < lines.length; i++) {
        print(lines[i]);
        cursorNames.push(lines[i]);
    }
    print(cursorNames[0]);
    var curs = path + cursorNames[1];
    var curs2 = path + cursorNames[2];
    var curs3 = path + cursorNames[3];
    var curs4 = path + cursorNames[4];

    function onFrameDrawing() {
        var mX = ccbGetMousePosX();
        var mY = ccbGetMousePosY();
        var invcur = ccbGetCopperCubeVariable("invcurs");
        var tex = ccbLoadTexture(curs);

        switch (invcur) {
            case 1:
                tex = ccbLoadTexture(curs)
                break;
            case 2:
                tex = ccbLoadTexture(curs2)
                break;
            case 3:
                tex = ccbLoadTexture(curs3)
                break;
            case 4:
                tex = ccbLoadTexture(curs4)
                break;
            default:
                tex = ccbLoadTexture(curs);
        }
        ccbDrawTextureRectangleWithAlpha(tex, mX - 4, mY - 4, mX + 28, mY + 28);

        ccbSetCursorVisible(false);
    }

    ccbRegisterOnFrameEvent(onFrameDrawing);

}

I think is much easier to use JSON object here:

var yourCursorObject = {
name : [""],
path: [""],
image: []
};

Does coppercube support JavaScript Json?

In the meantime PLEASE start migrating your JSON-using applications over to Crockford’s json2.js. It is fully compatible with the ECMAScript 5 specification and gracefully degrades if a native (faster!) implementation exists.

There are two primary methods for handling JSON: JSON.parse (which converts a JSON string into a JavaScript object) and JSON.stringify (which convert a JavaScript object into a serialized string).

I'm struggling with js trying to figure out what works and what doesn't, I'm piecing bits together and hoping it works :)
But yes I agree I need to start using JSON, I'm trying to do my own inventory and other things
I'll have a look at the link, thank you
