seiyria Posted February 20, 2014 Share Posted February 20, 2014 So I'm currently trying to make a sprite that just moves around in a circle forever. I was using the example found here: http://examples.phaser.io/_site/view_full.html?d=physics&f=angular+velocity.js&t=angular%20velocity as a base. My code for creating said sprites looks like this: @map.createFromObjects 'PlatformLayer', 45, 'platforms', 0, true, false, @circPlatforms @circPlatforms.setAll 'body.allowGravity', false @circPlatforms.setAll 'body.immovable', true @circPlatforms.forEach ((platform) => platform.radius = (+platform.radius or 1) platform.rotAngle = +platform.rotAngle or 0 @game.time.events.loop 1, ((platform) => platform.body.velocity.x = 0 platform.body.velocity.y = 0 @game.physics.velocityFromAngle platform.rotAngle, platform.radius*32, platform.body.velocity platform.rotAngle = ++platform.rotAngle % 360 ), @, platform ), @In Tiled I assign a rotAngle (the current spot in the rotation) and a radius (the number of tiles I'd like it to cover). Unfortunately, I have no idea what I'm doing. I can't seem to get the sprite to move faster along the circle (increasing the speed parameter just seems to make the circle larger and body.angularRotation, body.angularAcceleration, and body.speed don't seem to help either), and I'm not at all certain how to ensure the radius in tiles (a tile for me is 32x32). Also, when this sprite gets to the end of a full rotation, it is not where it started, it's somewhere off to the top-left. I can't figure out how to determine why it's doing that. Overall, I'm just sorta confused about this whole ordeal. Any ideas? Link to comment Share on other sites More sharing options...
seiyria Posted February 21, 2014 Author Share Posted February 21, 2014 I should add that I now have a demo viewable here: http://seiyria.com/defiled-dreams If it's watched while it makes loops, it's pretty obvious that it falls out of sync with itself.
