The Spear Stickman

🏹 The Spear Stickman: A Study in Projectile Trajectories

The Spear Stickman strips combat down to its oldest mathematical form: ballistics. Unlike modern shooters with hit-scan weapons (instant travel), this game requires the player to internalize the physics of a parabolic arc. It is a duel simulation where the only variables are the angle of release and the force applied, pitted against the constant of gravity.

The game serves as an interactive lesson in kinematics. The player must adjust their aiming vector in real-time based on the enemy's changing elevation and distance. The "Ragdoll" physics engine adds a layer of unpredictability; an enemy hit in the shoulder may spin due to the transfer of kinetic energy, whereas a headshot terminates the physics simulation instantly.

🎯 Mechanics: The Hitbox Hierarchy

Understanding the damage model is essential for longevity in the "Endless" mode:

• Headshots (Critical): The skull hitbox is small but offers a 1-hit kill. This rewards high-risk, high-arcing shots that drop vertically onto the target.
• Body Shots: Hitting the torso requires multiple spears. This is safer but allows the enemy more time to return fire.
• Limbs: Hits to arms or legs do minimal damage but can physically push the enemy model back due to momentum transfer.

🧠 Strategic Analysis

1. The "High Arc" Technique

Novice players shoot straight. Expert players shoot high. A spear falling vertically has a higher probability of hitting the head hitbox than a spear traveling horizontally, which is likely to hit the chest or be blocked by a shield.

2. Apple Hunting & Economy

The secondary objective—hitting the apple above the enemy—serves as a risk/reward mechanic. It requires a precise trajectory that misses the lethal hitbox. Successfully farming coins allows for equipment upgrades (helmets/armor) which increase your own hitbox durability.

🎮 Controls & Feedback

The input system is drag-and-release, simulating the tension of a bow or throwing arm.

• Aim: Drag mouse backwards to set power and angle.
• Fire: Release left mouse button.
• Visual Cues: A trajectory line appears briefly to aid in aiming adjustments between shots.
