Part 1: Linear Forces

-

- The first - and perhaps easiest - part of implementing any rigid body physics system is getting the entities in your scene to move in response to linear forces. - With this implementation alone, you can achieve an interesting level of realism in your 2D (and even 3D) scene. -

-

- Let's begin by recalling the relationships between acceleration, velocity, and position. -

-

- Knowing all this, you should be able to understand the following source code fairly easily; - 

-                        
-function update(dtSeconds) {
-    // Add up the forces acting on the circle
-    const GRAVITY = 9.8;
-    const lGravityForce = vec2(0, -1.0 * (lCircle.mass * GRAVITY));
-    lCircle.force = addVec2(lCircle.force, lGravityForce);
-
-    // Figure out acceleration (a = F / m)
-    const lCurrentAcceleration = scaleVec2(lCircle.force, 1.0 / lCircle.mass);
-
-    // Calculate the new velocity: v = v0 + a * t
-    lCircle.velocity = addVec2(lCircle.velocity, scaleVec2(lCurrentAcceleration, dtSeconds));
-
-    // Update the position based on velocity: x = x0 + v * t
-    lCircle.position = addVec2(lCircle.position, scaleVec2(lCircle.velocity, dtSeconds));
-
-    // Update the model matrix accordingly
-    lCircle.model = translateMatrix(mat4(), lCircle.position.x, lCircle.position.y, 0);
-
-    // Reset the force vector for the next update
-    lCircle.force = vec2()
-}
