For our shooter game, we'll use voxel collision and a little bit of manual intersection. Unfortunately, all the physics libraries are large, so we don't have space to cover their APIs here. However, Cannon.js and Physi.js have examples specifically for use with Three.js available from their project pages.

Voxel collision

If we try to walk around our world now, we'll just fall through the floor. Let's create a function to check for collision between the player and the voxel world:

function checkPlayerCollision(player) { player.collideFloor(floor.position.y); var cell = mapCellFromPosition(player.position); switch (cell.char) { case ' ': case 'S': break; case 'X': moveOutside(cell, player); break; } }
