JavaScript Calculate the x and y based on bearing
I have a screen where I would like to calculate the next x and y based on angle. The first footstep is this example starts at Step 1. How can I calculate the next footstep where I want to increase going forward by 120 and the side step needs to weave in and out of about 60.
Please bear in mind that the starting point could be x = 100, y = 100 with the angle being 180 so the footsteps would have to then be going up the y axis.
I've attempted the following Javascript but the footsteps seem to get confused:
this.startingFootPrintX = Math.floor(Math.random() * 1000) + 20; //Random number between 20 and 1000
this.startingFootPrintY = Math.floor(Math.random() * 560) + 20; //Random number between 20 and 560
this.startingAngle = Math.floor(Math.random() * 340) + 20; //Random number between 20 and 340
startFootSteps();
startFootSteps(){
console.log(this.startingFootPrintX);
console.log(this.startingFootPrintY);
this.startingFootPrintX = Math.round(Math.cos(this.startingAngle * Math.PI / 180) * 120 + this.startingFootPrintX);
this.startingFootPrintY = Math.round(Math.sin(this.startingAngle * Math.PI / 180) * 60 + this.startingFootPrintY);
setInterval(function () {
startFootSteps();
}, 3000);
}
