Bullet lifespan (Phaser 3)

Since Phaser v3.50.0 the WORLD_STEP event passes the Arcade Physics delta time. You can use it to implement precise bullet lifespans. Bullet lifespans are slightly simpler than bullet ranges since no distances need to be calculated. function fireBullet (bullet) { // … bullet.setState(BULLET_LIFESPAN); } function updateBullet(bullet, delta) { bullet.state -= delta; if (bullet.state <= 0) { bullet.disableBody(true, true); } }

Bullet range (Phaser 3)

Here’s a way to make bullets expire at a certain distance traveled, taking advantage of newVelocity. It’s a little more efficient to make bullets expire after a physics-time limit is reached instead. Phaser v3.50.0 will make that easier. function fireBullet (bullet, x, y, vx, vy) { // … // Set the range in pixels bullet.state = 300; } function updateBullet (bullet) { bullet.state -= bullet.body.newVelocity.length(); if (bullet.state <= 0) { bullet.disableBody(…
