Tank Battle: Master Artillery Physics and Dominate the Battlefield

The Physics of Tank Battle

Tank Battle isn't just "aim and shoot." There's a real physics simulation running under the hood, and understanding it gives you a massive advantage. Every shot follows a ballistic trajectory affected by gravity, power, and wind.

Think of it like this: your shell is launched at an angle with a certain force. Gravity pulls it down over time. Wind pushes it sideways. The terrain can block its path. Understanding these forces turns random lobbing into precision strikes.

How the Physics Engine Works

The Three Forces

1. Gravity (0.3 units per tick) Gravity constantly pulls your shell downward. Higher angles mean more time in the air, which means more time for gravity to act. Low angles create flat trajectories but less distance.

2. Power (scaled at 0.8x) Your power setting determines initial velocity. At 100% power, your shell launches at 0.8x multiplied by the power value. This scaling prevents shots from flying off the screen while maintaining satisfying arcs.

3. Wind (scaled at 0.15x) Wind ranges from -20 to +20 and applies a constant horizontal force to your shell. Positive wind pushes right, negative pushes left. At wind 20, your shell drifts significantly - you'll need to compensate by aiming into the wind.

Trajectory Calculation

The game simulates 500 physics steps per shot. At each step:

1. Horizontal velocity is adjusted by wind (multiplied by 0.15)
2. Vertical velocity is adjusted by gravity (0.3 added downward)
3. Shell position updates
4. Collision detection checks for terrain or tank hits

This means a shot at 45 degrees and 50% power in zero wind creates a symmetric parabolic arc. Change any variable and the arc changes dramatically.

Angle and Power Fundamentals

The 45-Degree Rule

In classic physics, 45 degrees gives maximum range with no wind. In Tank Battle, this holds approximately true:

• Below 45°: Flatter trajectory, faster travel, shorter range
• At 45°: Maximum distance for given power
• Above 45°: Higher arc, longer hang time, shorter ground distance

Power Control

• Low power (20-40%): For nearby targets. Gives you more control and smaller error margins.
• Medium power (40-70%): For mid-range engagements. The sweet spot for most shots.
• High power (70-100%): For distant targets or lobbing over terrain. Harder to control but necessary for long-range hits.

Wind Compensation

Rule of thumb: For every 5 units of wind, adjust your angle by approximately 3-5 degrees into the wind.

Examples:

• Wind +10 (right): Aim slightly left of your target
• Wind -15 (left): Aim noticeably right of your target
• Wind 0: No compensation needed

Advanced: Stronger wind requires exponentially more compensation at longer ranges because the wind acts over more time. A shot that travels 3 seconds in wind +10 drifts more than three times as much as a 1-second shot.

Terrain: Your Best Weapon

Destructible Terrain

Every explosion creates a crater with a radius of approximately 40 pixels. This permanently deforms the terrain, creating opportunities:

Terrain Destruction Tactics:

1. Undermine enemies: Shoot the ground UNDER an enemy tank. If you destroy enough terrain beneath them, they'll drop into the crater, changing their position and making them harder to hit (but also harder for them to aim).

1. Create cover: Deliberately build up terrain walls by NOT destroying certain areas. The terrain blocks shots, so strategic craters can create defensive positions.

1. Open firing lanes: If terrain is blocking your shot, destroy it with a deliberate miss. Next turn, you'll have a clear path to the target.

Reading the Terrain

The terrain is procedurally generated using layered sine waves, creating hills and valleys:

• Hills provide natural cover but limit your shooting angles
• Valleys leave you exposed but give you wider angle options
• Peaks are great positions for lobbing shots over terrain

Terrain Regeneration

Between rounds, terrain is completely regenerated. Player positions are reshuffled. This means:

• Don't rely on memorized terrain patterns
• Adapt your strategy each round
• The terrain you destroyed last round won't help you this round

Scoring System Explained

Understanding scoring helps you prioritize targets and play strategically.

Placement Points (Rank-Based)

At the end of each round, surviving tanks are ranked:

• 1st place: ~100 points
• 2nd place: ~70 points
• Last place: ~10 points

The exact formula scales linearly between 100 (max) and 10 (min) based on your rank among all players.

Elimination Bonus

Each tank you personally destroy earns you +10 bonus points. These bonuses are cumulative across all rounds.

Strategy implication: Actively hunting eliminations adds up. In a 3-round game with 6 players, getting 3 eliminations adds 30 bonus points - potentially the difference between 1st and 2nd place.

Total Score

Final Score = Sum of Round Placements + Total Elimination Bonuses

This system rewards both survival AND aggression. You can win by:

1. Surviving consistently (high placement points each round)
2. Eliminating aggressively (accumulating bonus points)
3. Both (the ideal strategy)

Tank Combat Strategy

Target Selection

Against many players (4+):

• Target the weakest tank (lowest HP) for quick elimination bonuses
• Avoid the strongest players early - let others weaken them
• Position matters: don't fire at distant targets when nearby threats exist

In 1v1 or small groups:

• Every shot counts - accuracy over aggression
• Wind compensation becomes critical
• Take your time with the 30-second turn timer

HP Management

Each tank starts with 3 HP. There's no healing between turns within a round.

• At 3 HP: Play aggressively, you can afford to take risks
• At 2 HP: Be careful, one more hit might not finish you but you're vulnerable
• At 1 HP: Survival mode - every shot matters. Consider defensive positioning

The 30-Second Turn

You have 30 seconds per turn. If time runs out, your tank automatically fires with its current angle and power settings. Use this knowledge:

• Adjust angle first (usually needs the biggest change)
• Fine-tune power second (smaller adjustments)
• Fire with confidence - don't wait until the last second

Game Presets

Advanced Tactics

The Ranging Shot

Not sure about your aim? Fire a ranging shot at slightly wrong power. Watch where it lands, then compensate next turn. This works because:

• The terrain doesn't change between turns (within a round)
• Wind stays the same for the entire round
• You learn the exact trajectory curve

Wind Reading

Pay close attention to the wind indicator. Experienced players develop an intuition for wind compensation:

• Light wind (±1-5): Minor adjustment, aim slightly into wind
• Moderate wind (±6-12): Significant adjustment needed
• Strong wind (±13-20): Major aim correction, consider power adjustments too

Multi-Target Awareness

With up to 8 players, the battlefield gets chaotic. Keep these priorities:

1. Don't ignore tanks behind you
2. Track who's targeting you (they'll aim at you again next turn)
3. Sometimes it's better to target someone who's NOT expecting it
