  1. Just glancing at that code, your chain of if/elses is written in such a way that you can never actually get at this portion: else if((this.cursor.right.isDown || this.cursor.left.isDown) && this.jump.isDown){ this.player.body.velocity.x= 200; this.player.body.velocity.y=-200; } The first two conditions checking for left & right will always be accessed before this above one, and that's because you've chained all those ifs to be dependent on each other; if you can't do if 1., try if() 2. If you can't do if() 2, try if () 3, and so on. Instead, something like the below might work - though I haven't checked it. Ideally you want to check the jumping code independent on whether you're pressing left or right. if(this.cursor.right.isDown){ this.player.body.velocity.x= 200; this.player.animations.play('correr', 5, true); this.player.scale.x=1; } else if(this.cursor.left.isDown){ this.player.body.velocity.x= -200; this.player.animations.play('correr', 5, true); this.player.scale.x=-1; } if(this.jump.isDown && this.player.body.wasTouching.down) { this.player.body.velocity.y= -400 } else { // Whatever you want to do if you're NOT jumping }
  2. @deepsky88 There is your problem: var esperienza = 0 this is a local variable, not a member property of your Game State; it's scope is only wherever it was declared - the boot function. So assuming you mean the preload() or create() functions, if you declare it like the below instead, it SHOULD be visible to the physics callback: this.esperienza = 0;
  3. @deepsky88 Hard to say from just that snippet, but I'm guessing "this.esperienza" doesn't exist on 'this', so performing a += 10 operation returns the NotANumber (NaN) property because it's operating on a property that can't be accessed. First thing: has this.esperienza actually been created, and what is it: just a basic type like a Number, Sprite etc? Second, it's always worth debugging yourself to see why a variable or object isn't behaving as expected: either adding the debugger breakpoint (perhaps after this.esperienza += 10 assignment) to see what the scope of your anonymous function contains, though you can do the same with just a console.log(this) in the same place (though sometimes with Phaser that can cause a cascade of console.logs!)
  4. There's no way to completely block the JS code from the User on the client-side, however there are a few ways to made it harder for them: Uglify the JS as much as possible, so inspecting the code is (close to) meaningless. IIRC you can even uglify the 'top level' so namespaces are obscured. Someone could still use a 'beautifier' to reformat it all, but with no human-readable var names, comments, etc. it'd be an exercise in patience just to work out how your game works. Honestly if you're publishing a game this is the very least you should do to 'protect' the code. None / little of your code should be publicly accessible from the console anyway. If possible, declare your new Phaser.Game() as a private instance somewhere, that makes it harder for a curious User to inspect the game's current state from the console. IMO it's good practise anyway to make sure you don't extend the window/document object, so it's a good habit to get into. @Zampano just quickly looking at your game, you've declared 'player' as a global variable within Game.js - this is why it's available in the console. Maybe you should think about wrapping your .js files with anonymous functions so that all the code within is 'private'. That causes its own problems however, as you still need to expose things like your 'x_player' class globally (or through something like NodeJS imports), so the main Game code can access it later.
  5. Thanks @rich for clarifying those two things. I did presume V3 was probably still a fair bit in the future, but I was very curious / anxious that the versioning would be a major revision to the framework's structure. Good to hear that eventually not too much will require refactoring :-D
  6. Just wondering as an aside (and apologies if this was already asked & answered), but what is the expected difficulty curve between updating code from Phaser 2 to Phaser 3? I appreciate v3 is a WIP, but are there likely to be many gotchas but otherwise a fairly simple transition? Or will it be something similar to the angular framework where there was a wholesale top-to-bottom change between version 1 & 2+. If not done already it might be worth an article from the Phaser team themselves. I have a few WIP projects and part of me thinks it might be worth waiting until Phaser 3 arrives, as I'm worried I may have to refactor large chunks of my code...
  7. I see the plugin's a bit dormant ATM, I think, but perhaps you guys have had enough experience to answer what _seems_ like a simple question: Given I have a Phaser.Group() of Isometric.ISOSprite() acting as the 'floor' tile-map, is it possible to constrain the state's bounds based on this Group? The group will be dynamic so the number of sprites will change. I had initially thought simply going: game.world.setBounds(myGroup.x, myGroup.y, myGroup.width, myGroup.height); would work, but of course those coordinates don't accurately reflect the 'true' dimensions of the isometric grid, given the plugin projects the coordinates. I tried a couple of guess/combinations, but I always got 'weird' bounds as a result. Any ideas? Hopefully the answer's simple!
  8. Apologies if this has either been asked before, or I'm misunderstanding how to use RenderTextures I have a renderTexture that's outputting the contents of a Phaser.Image(), which in turn contains an instance of Phaser.BitmapData(). In my update() loop, I want to update the position of some geometry drawn in the BitMapData, but those changes are never seen in the RenderTexture. What would be the reason for this? Like I said I could be misunderstanding how & why you might want to use a RenderTexture, but this portion of my code will be quite expensive & updated regularly - so it seemed like a good idea to pass this logic out to the GPU if possible, which is what a RenderTexture allows, right? Am open to some better ideas if I do indeed have the wrong idea! Below is the code: it's written in TypeScript and the class extends Phaser.Sprite(), so hopefully it makes sense even to those only familiar with JS. As you can see in my update() I'm redrawing a bitmapData.circle() with a new x position, then rendering back to the RenderTexture again. However, the circle never moves from its original position of 0. If I console.log out the x value, it's clearly update per tick. constructor(game: Phaser.Game, map: any) { const texture = new Phaser.RenderTexture(game, map.widthInPixels, map.heightInPixels, key); const bitmap = new Phaser.BitmapData(game, 'BITMAP', map.widthInPixels, map.heightInPixels); super(game, 0, 0, texture); this.bitmap = bitmap; this.image = new Phaser.Image(game, 0, 0, this.bitmap); this.texture = texture; // Other code to add this .Sprite() to the stage. } private update() { const bitmap = this.bitmap; bitmap.clear(); bitmap.circle(x, 100, 50, 'rgb(255, 255, 255)'); this.texture.render(this.image); x += 10; }
  9. Great, that's interesting @feudalwars thanks for the tips. So am I right in thinking your suggestion is more of a binary "you either see it or don't" mechanic, right? I wonder then how to create the same vision 'blob', only with 3 states of visibility: black => half-opacity => visible, which has been where the performance started to drag. I thought of keeping a cache of sprites' movements, so that I could set the 'last' location as half-opacity once you left the radius, but that because expensive even to render those cached areas. The renderTexture suggestion sounds interesting - would it be more performant than using Phaser.Image() <= Phaser.BitMapData() ?
  10. First time poster, long time lurker. short version: is it possible to chain, or merge the blendModes of multiple display objects? Say: I have Phaser.Image() with blendMode to MULTIPLY, its contents varying rgb() values to either hide or partially-hide what's beneath Above it could be another display object, also set to MULTIPLY, but with rgb(255, 255, 255) - AND - the blendMode chains with the Phaser.Image() so this object is transparent It doesn't feel possible, but I'm not 100% sure, or what a good alternative might be. I'm not even sure I'm explaining this correctly. Why? Well. I'm trying to build a functioning, dynamic 'Fog of War', as seen in RTS games. Ideally I want something like in 'Starcraft', where areas on the map can be: Hidden / unexplored Already explored, but outside any 'unit' radius of visibility Currently without the visibility of a player sprite Yes, in principle this is fairly easily done with a grid of squared tiles, but I want to do something a little ... rounder and more dynamic, like proper 'blobs' of fog rolling back and forth rather than arbitrary square tiles flicking ON/OFF. It seems like something you could do with WebGL Stencil Buffers but ATM that feels beyond my capabilities. So my initial idea was to have a Phaser.Image(), blendMode set to MULTIPLY, within it a BitMapData() grid of circular 'tiles', the fill() different shades of white-black depending on hidden/explored/visible. It's a bit crude & performance isn't great once a lot of player sprites start moving on the map; I'm experimenting on ways to improve speed & one idea was if it was possible to chain blendModes so the bigger fog grid didn't have to make so many re-renders. Hopefully that makes sense?
