Playing mobile games on a computer should not require complicated scripts or confusing setup pages. The ideal experience is simple: open the Android game, mirror it to the computer, drag controls onto the screen, bind keys, and start playing with a keyboard and mouse layout that feels natural.
That is where LaiCai's drag-and-drop key mapping system is useful. Instead of forcing every player into the same fixed preset, LaiCai lets you build your own control layout visually. You can place movement, fire, aim, jump, skills, camera control, inventory, map, and shortcut actions exactly where your game needs them.
What Is Drag-and-Drop Key Mapping?
Drag-and-drop key mapping means you place control points directly on top of your mirrored Android screen. If a mobile game has a virtual joystick, place a movement control on it and bind it to W, A, S, and D. If the game has fire, aim, jump, skill, backpack, map, or interact buttons, place keyboard or mouse controls on those buttons and decide which keys trigger them.
The setup is visual. What you see on the screen is what you configure. You do not need to write scripts, calculate screen coordinates manually, or guess where a touch action will land.

Build a PC-Style Control Layout in Minutes

Fair Play Reminder
Use key mapping responsibly and follow each game's rules. Do not use tools for cheating, unfair automation, recoil scripts, account abuse, or anything that violates game terms.
