Destroy all three enemy tanks. You and your opponent fire in turn.
Controls
Set ANGLE (θ, 5°–85°) and
POWER (V, 20–100), then FIRE.
The trigonometry
Your shell leaves the barrel at speed V, angle θ. That one velocity splits
into two independent parts:
Vx = V · cos(θ) → carries it across Vy = V · sin(θ) → carries it up, then gravity takes it back down
Raise θ and you trade distance for height.
45° gives maximum range — that is the angle where
sin and cos are equal, so the shell gets the best possible split between across and up.
Live Trig Breakdown
The centre panel recalculates as you move the sliders, before you commit.
Read Vx and Vy off it and you can reason about where the shell will land instead of guessing.
Ranging in
Your first shot is not supposed to hit. Watch whether it
falls short or long, adjust, and fire again. Bracketing the target over two or three shots is
how real artillery works — a miss is information, not a mistake.
