Game Development 101: C# and Unity

Create a sticky ball from multiple spheres with a blue material and orange nodules as children, then add a rigid body with gravity and position nodules on the ground.

Create a Unity camera script that looks at the ball with a 1.5 unit offset above the ball, using a public ball reference.

Configure and control the sticky ball using y-axis rotation, translating input to a unit vector to apply force, and position the camera behind the ball for dynamic viewing.

Learn to make objects stick to a growing ball in Unity by using on trigger enter, isTrigger, and tag checks, while managing scale, camera distance, and collision behavior.

Import free asset packs, drag objects into the scene, detach children, and delete the parent; then tag as sticky, add convex mesh colliders with is trigger, and resize models.

Unlock multiple object categories in Unity with C# as the size grows. Disable isTrigger on objects and use a for loop to enable categories at sizes 1, 1.5, and 2.

Create a custom level in Unity by organizing assets into three size-based categories, using fences and ramps as boundaries and growth mechanics, and duplicating objects while keeping their category.

Display the ball mass in Unity with a top-left UI text object. Round the mass to two decimals, convert to string, and link the text to the ball.

Import royalty-free music and pickup sound effects into Unity, set a looping track that plays on wake, and use an audio source to play a one-shot on trigger enter.
