Bodies possess various properties:
pos: Vector, x: number, y: number.setPosition(x: number, y: number) for teleport and move(speed: number) for moving forward in direction of its angle.setScale(x: number, y: number) for setting and scale: Vector for getting scalesetAngle(radians: number) for setting and angle: number for getting and deg2rad(degrees: number) to convert to radians.setOffset(offset: Vector) for setting and offset: Vector for getting offset from the body center.Manipulate body attributes and update the collision system:
-// if omitted updateNow is true
const updateNow = false;
// teleport
box.setPosition(x, y, updateNow);
box.setScale(scaleX, scaleY, updateNow);
box.setAngle(angle, updateNow);
box.move(1, updateNow);
box.setOffset({ x, y }, updateNow);
console.log(box.dirty); // true
box.updateBody(); // Update the body once, when all manipulations are done
console.log(box.dirty); // false
box.group = group; // Immediate effect, no body/system update needed
console.log(box.dirty); // false
+// if omitted updateNow is true
const updateNow = false;
// this should be time scaled, 1 for example
const speed = 1;
// teleport
box.setPosition(x, y, updateNow);
box.setScale(scaleX, scaleY, updateNow);
box.setAngle(angle, updateNow);
box.move(speed, updateNow);
box.setOffset({ x, y }, updateNow);
console.log(box.dirty); // true
box.updateBody(); // Update the body once, when all manipulations are done
console.log(box.dirty); // false
box.group = group; // Immediate effect, no body/system update needed
console.log(box.dirty); // false
Step 5: Collision Detection and Resolution
Detect collisions and respond accordingly:
