Post Processing and Responsive Feedback

Game Feel

Now that our core mechanics and visuals are in place, it's time to add polish - the small aesthetic tweaks that dramatically change how a game feels to play.

Game design can be understood using the MDA Framework (Mechanics, Dynamics, Aesthetics), introduced by Robin Hunicke, Marc LeBlanc, and Robert Zubek.

• Mechanics -> the rules and systems we code;
• Dynamics -> how those systems interact during play;
• Aesthetics -> how the game feels and is experienced by the player.

This means that no matter how clever our mechanics are, players won't appreciate them unless they look, sound, and feel satisfying.

Game feel, as described by Steve Swink, is about maximizing the output from player inputs. In practice, this means exaggerating feedback and making every action feel responsive and impactful.

In this section, we will improve game feel through:

• post-processing (Vignette, Tonemapping, Chromatic Aberration, Film Grain);
• responsive visuals (like flipping the sprite based on movement input);
• particles;
• animation;
• lighting;
• audio feedback.

Post Processing

Post processing is a visual layer applied to the camera output.

It's added by:

• creating a Global Volume;
• generating a Volume Profile;
• adding post-processing overrides (Vignette, Chromatic Aberration, Tonemapping, Film Grain).

Key ideas:

• it affects the whole scene, not individual objects;
• subtle adjustments usually feel better than extreme ones.

Sprite Flipping & Responsiveness

When the player presses left or right, the character should immediately face that direction.

Using SpriteRenderer.flipX tied to horizontal input creates instant visual feedback.

Pivot Points Matter

For flipping to look smooth:

• open the Sprite Editor;
• select all animation frames;
• set Pivot to Centre;
• apply.

Why?

Flipping mirrors the sprite around its pivot point. If the pivot is off-center:

• the sprite appears to snap sideways;
• animations jitter;
• colliders may misalign.

Keeping the pivot centered (and collider offset aligned) ensures stable, clean mirroring.
