💣 炮弹对决Cannon Duel
在线炮弹对决：和电脑轮流开炮的回合制炮战。调整炮管角度和发射力度，算好随风向变化的风力，把炮弹打到对方炮台上。炮弹会在地面炸出弹坑，地形随之改变。双方各有 100 点血，先被打光的一方输。电脑有三档难度，会显示上一发的轨迹，键盘、鼠标和触屏都能玩。Cannon Duel online: a turn-based artillery battle against the computer. Set the barrel angle and firing power, allow for the wind that changes every shot, and land your shell on the enemy cannon. Shells blast craters and reshape the ground. Each side has 100 health — the first to lose it all loses. Three computer levels, a guide showing your last shot, and keyboard, mouse or touch controls.
拖动滑块设置角度和力度后点“开炮”；键盘 ←→ 调角度、↑↓ 调力度、空格开炮。虚线是你上一发的轨迹。Set angle and power with the sliders, then press Fire; on a keyboard ←→ change the angle, ↑↓ the power and Space fires. The dotted line shows your last shot.
玩法说明与常见问题How to play & FAQ
「炮弹对决」怎么玩？How do I play Cannon Duel?
你是左边的蓝色炮台，电脑是右边的红色炮台，轮流各开一炮。炮弹受重力下落，还会被风吹偏（画面上方的箭头显示风向和强弱，每回合都会变）。炮弹落地爆炸，离爆炸点越近伤害越大，直接命中额外加伤。爆炸会炸出弹坑，炮台也会跟着下沉。You are the blue cannon on the left, the computer is the red one on the right, and you take turns firing. Shells fall under gravity and drift with the wind (the arrow at the top shows its direction and strength, and it changes every turn). Shells explode on impact — the closer the blast, the bigger the damage, with a bonus for a direct hit. Blasts dig craters, and cannons sink into them.
电脑会作弊吗？Does the computer cheat?
电脑和你使用完全相同的物理和风力，只是会根据难度在计算出的瞄准值上加入不同程度的误差。It uses exactly the same physics and wind as you; depending on the level it just adds more or less error to its calculated aim.
怎么快速找准？How do I find the range quickly?
先固定角度只调力度：如果上一发打近了就加力，打远了就减力，再考虑风向微调。Keep the angle fixed and adjust only the power: more if you fell short, less if you overshot, then nudge for the wind.
