Ld00d Posted January 22, 2017 Share Posted January 22, 2017 Sorry if this has been covered already, but I wasn't able to find anything via searches. I have a game I started with the boilerplate. In the TitleScreen, I've added a "Play" button that appears in the lower center of the canvas. The button is displaying fine, but the clickable area appears to be a box roughly the size of the button, but starting at the center of the button. So the button actually appears centered on the position I placed it, but the clickable area is if the top left was at that position. I was going to dig into the melonjs code and determine what's happening, but I wanted to see if this is because of something I'm doing incorrectly. melonJS Game Engine v4.1.0 var PlayButton = me.GUI_Object.extend({ init: function(x, y) { var settings = {}; settings.image = "btnplay"; settings.framewidth = 250; settings.frameheight = 100; // super constructor this._super(me.GUI_Object, "init", [x, y, settings]); // define the object z order this.pos.z = 4; }, onClick: function () { // Change to the PLAY state when the button is clicked me.state.change(me.state.PLAY); return true; } }); game.TitleScreen = me.ScreenObject.extend({ /** * action to perform on state change */ onResetEvent: function() { // Load background image me.game.world.addChild( new me.ImageLayer(0, 0, { image : "launch", z: 0 // z-index } )); me.game.world.addChild( new PlayButton(480, 480), 10 // z-index ); }, /** * action to perform when leaving this screen (state change) */ onDestroyEvent: function() { // TODO } }); Also, I have the z-index at 10 because 1 wasn't working for some reason.

obiot Posted January 23, 2017 Share Posted January 23, 2017 probably a consequence of changing the default anchor point to 0.5 for all renderables, cumulated to this issue : https://github.com/melonjs/melonJS/issues/833 this will be fixed in the next 4.2.0 version, but in the mean time, you should be able to fix it by adding `this.anchorPoint.set(0, 0);` in your constructor. sorry for the annoyance !
