I am trying to pass the values I get from my form into a constructor function called Robot(); I have no problem accomplishing this in the console by passing in the arguments myself. for ex: var travis = new Robot("Travis","Blue","medium"); if i were to enter something like travis.speed it would return 1 as expected.
but when I try using my form on the website to do so and test it out the console says Travis is not defined.
I feel like I am doing everything correct, but apparently I am not. If someone could please help me out I would be much appreciative.
my script.js:
var $canvas = $("canvas");
var ctx = $canvas[0].getContext("2d");
function Robot(name, color, robotBuild){
this.name = name.toLowerCase();
this.robotBuild = 'medium';
this.health = 100;
this.speed = 1;
this.strength = 1;
this.powerState = false;
this.maxStrength = 100;
this.minStrength = 1;
this.maxSpeed = 10;
this.minSpeed = 1;
this.maxHealth = 100;
this.minHealth = 0;
this.points = 0;
//ROBOT POSITION VALUES
this.posX = 0;
this.posY = 0;
//ROBOT PHYSICAL PROPERTIES
this.robotWidth = 10;
this.robotHeight = 10;
this.robotColor = color.toLowerCase();
}
Robot.prototype.draw = function(){
ctx.beginPath();
ctx.rect(this.posX, this.posY, this.robotWidth, this.robotHeight);
ctx.fillStyle = this.robotColor;
ctx.fill();
ctx.closePath();
this.powerState = true;
};
Robot.prototype.power = function(powerState){
powerState.toLowerCase();
if(powerState === "on"){
this.powerState = true;
}else if(powerState === "off") {
this.killRobot();
}else {
console.log("Input must be a value of 'on' or 'off'.");
}
