  1. There is a POLYGON SCAN game at https://www.html5pcode.com/a1ypolygonscan.htm that was designed to teach the art of coding. It uses structured programming, so it is easy to follow the logic of the design. The game is divided into small self contained pieces. It has a main program and a subprogram. The subprogram has routines that perform specific tasks when they are called by the main program. The game has links to YouTube videos that describe the operation of the main program and the subprogram routines. Once you learn how to design games like this one, you can go on to design your own games
  2. Hi All, Below is my project url please visit : http://111.93.53.134/digital/test/polygon/ Now my question is that i am creating a polygon at run time and add physics to polygon. When the polygon collides with matter body a horizontal redline is drawn and when i click on the down arrow button then another metal spring collides with polygon shapes then a blue line draw and you can drag the blue line. So i have to take the snapshot of only that polygon and redline which is beneath the polygon and that blue line which is being dragged and show them in the grid box 1,2,3,4. T
  3. Hi everyone, I'm working on a javascript clone of superhexagon (https://www.superhexagon.com/) in order to learn to use Phaser 3. I was wondering what was the best way to generate the same shape multiple time with some rotation tweek and animate them. I need generate them, display them, once they display I need to be able to rotate them and scale them down. Once their scale <= 0 I need to hide and destroy them. I know I need to build a kind of Factory but I can't figure out how to do it with gameObj.add.arc Could you point a part of doc or source code I can dig in t
  4. I'm trying to apply physics to a animated sprite. I used PhysicsEditor to generate the JSON and loaded the polygon shape for the first frame. Collision detection is not happening when i try to clear the shapes and load the polygon dynamically with respect to animation. Is there any method to clear and load the polygon dynamically to detect collision. Any thoughts ?
  5. Hello, I am new to babylonjs and am trying to extrude a non regular polygon towards the positive y direction. Going through the doc I couldn't find a way, it always extrudes it in the negative y direction. I found a hack using mesh.position.y += depth; but is there any other way of doing this ? Playground link : http://www.babylonjs-playground.com/#2EYZPE#7 Thanks.
  6. Hello everybody :-) I'm trying to use ExtrudeShape for creating a building shape and am having trouble with the cap. I understand that the cap is not tessellated (triangulated) so it would be faster. But when I have concave angles in the shape, it doesn't look good. I also tried using Ribbon for the roof polygon somehow, but the tessellation doesn't happen here either of course. Here is my code: http://www.babylonjs-playground.com/#1KQZAF#0 I tried using PolygonMeshBuilder but the mesh is rotated the way I don't want it to and some walls keep dissapearing depending on
  7. Hello there, Is it possible to create destructible terrain in HTML5 and box2d Video examples : Box2d Destructable terrain.mov Box2d Destructable terrain 2.mov Any help in this direction would be much appreciated. Thanks Again
  8. My sprites are often passing through polygons that they should be bouncing off of. I've tried to research this and all I could find is that the fps may be too low to always detect the collision but surely the game engine should be able to handle this? Interestingly, if I use setCircle() my colliding sprites never pass through even with much higher velocity. Why would a polygon I define behave differently than setCircle() ? Here is a demonstration: //phaser.io/sandbox/xeGQxHis
  9. Hey. I am trying to using 2 polygons as mask for a sprite group. It seems to work with drawRect perfectly, when I use more than 1 (as in the example image). But whenever I try to use 2 polygons, it just apply the first one created as mask. One polygon is above the window, one being the window itself. (see the code). I have provided my example code here. poly = new Phaser.Polygon( { x: 0, y: 0 },{ x: 0, y: 255 },{ x: 153, y: 255 },{ x: 154, y: 218 }, { x: 176, y: 213 },{ x: 165, y: 215 },{ x: 165, y: 215 },{ x: 176, y: 213 }, { x: 19
  10. Hello! I am the P2 physics. I have a sprite scaled. My problem is that the polygon loaded to the sprite does not scale with it. It is possible to scale the polygon?
  11. Hi, I'm trying to get a sprite to spawn within a polygon I've drawn in Tiled. I've imported the polygon like so: this.bunyipSpawnZone = new Phaser.Polygon(polygonSpawn[0][0],polygonSpawn[0][1],polygonSpawn[1][0], polygonSpawn[1][1],polygonSpawn[2][0],polygonSpawn[2][1],polygonSpawn[3][0], polygonSpawn[3][1],polygonSpawn[4][0],polygonSpawn[4][1],polygonSpawn[5][0],polygonSpawn[5][1]); polygonSpawn is the corresponding Tiled map object. Which is an array where [0] is the x coord and [1] is the y. this.bunyipSpawnZone returns a Phaser.Polygon
  12. Hello, I'm trying to export a model which is about 400,000 Polys. I know the maximum export is somewhere around 60, 000 for any one mesh. I am thinking about breaking and exporting the mesh in different parts. Will this lead to issues in the scene? Also, what is the best polygon count for a babylon scene for efficiency in web and mobile? Finaly, what is the maximum polygon count for a babylon scene before it crashes? Thank you in advance!
  13. I'm using P2 physics, and I'm creating a relatively intricate border around the screen that I want balls to bounce against. I am scaling all assets on the screen for 3 different aspect ratios, depending on the user's screen size. I create the border like this: bgOverlay = otherSpriteGroup.create(gameWidth / 2, gameHeight / 2, "bgOverlay"); bgOverlay.anchor.setTo(0.5, 0.5); bgOverlay.scale.setTo(scale.x, scale.y); bgOverlay.body.clearShapes(); bgOverlay.body.loadPolygon("physicsData", "bgOverlay"); bgOverlay.body.setCollisionGroup(otherCollisionGroup); bgOverlay.body.collides(bubbleCol
  14. I have this code to add a rectangle in phaser and works fine but it fills with a solid color and i want some transparency in my poly. Is that possible? poly = new Phaser.Polygon(p_1, p_2, p_3, p_4); graphics = game.add.graphics(0, 0); graphics.beginFill(0xFF33ff); graphics.drawPolygon(poly.points); graphics.endFill();
  15. Hey there So, this is my first post in here, i hope everybody is good out there, let's go straight into the issue. I'm new to Phaser.io, and I'm intending to use it to create a hill climber clone. I have successfully create car like shapes (following a couple of online tutos) but still very confused about how to create the land on which the car will run. To make it clearer, here's an illustration of what i exactly want: So basically, the original game introduces 2+ types of ground, that are the bridges, land, water, ... I need to implement only two types. I
  16. I found this topic where it says that graphics object in phaser has hitArea that can be any shape. I searched Phaser docs but didn't find hitArea property. Is it moved somewhere else or is there some new way how to make graphics object clickable and call certain function when a click event happens? Also how can I show cursor hand when rollover a clickable graphics object? I forgot to ask is there some official phaser example for this functionality? PS: I even searched DisplayObject class but didn't find hitArea there.
  17. I was wondering are there any useful functions in Pixi.js which I can use in my Phaser 2.6 application to darken /brighten fill color of rectangles polygons etc...? For example make rgb(200, 150, 186) 10% darker. I might code a function like that in JS but should I? A tool that does the job but it works in NodeJS: https://www.npmjs.com/package/color
  18. 1. How can I draw closed polygon like the image above but without the diagonal black line that creates/finishes the polygon? 2. Or should I use Phaser.Polygon function at all? Is there some better solution? 3. Is it possible to create rectangle with mask smaller than the rectangle creating the image above? How would I apply border to this solution?
  19. Hi, I want to scale both sprite and .json physics file, is that possible and if so, how? I ve seen a few posts about that but no answers. Thank you
  20. Hey everyone, I am making a simple Worms-Armageddon-like game for educational purposes in my University course. I have a problem figuring out how to implement the following with Phaser. THE SETUP: 1.) Standard map with loaded Polygon from PhysicsEditor - image 1. I am using P2 physics but can change to Box2D if necessary. 2.) Making a hole with some weapon - image 2. THE PROBLEM: I believe I have an idea how to make the visual hole in the sprite, by using this example http://phaser.io/examples/v2/bitmapdata/alpha-mask (correct me if I am wrong or if there is a be
  21. I know I keep polluting this forum with my dumb questions.. BUT, what would be the easiest way to do a collision map not using tiles. I have seen some that make a solid color and tell the player they can't step into that color. I don't know how to get the color data for that so I was going to draw polygons and use ContainsPoint and kick the player out if he steps in or near and I couldn't figure out how to add points to a polygon already drawn so now I am running around the map and writing down my player location where I want my polygon points to be drawn and I felt stupid. More than usual. Wh
  22. Hi all, I've been trying to achieve a certain effect. I have two polygons, one of which is still while the other moves, and when they overlap, I want to have the still polygon on top. However, it always seems to be the moving polygon that remains on top. I've been trying to use groups following the example here, to no avail. Here is (most of) the offending code: var LayerTest = { preload: function () { }, create: function () { game.world.setBounds(-SIZE_X / 2, -SIZE_Y / 2, SIZE_X / 2, SIZE_Y / 2); var center_group = game.add.group(); center_group.z = 1; var center_hexagon_graphics = ne
  23. Hey, I'm trying to add a custom collision polygon for a hexagon. I've measured the corners of my hexagon in illustrator: 28, 055,1655,4828,00,480,16 When I try to implement it:game.physics.p2.enable(hexagon, true);hexagon.body.clearShapes();hexagon.body.addPolygon( {} , [[28,0],[55,16],[55,48],[28,0],[0,48],[0,16]]);The collision polygon is not visible at all (in debugger). I've never tried adding a custom polygon so I have no idea what I'm doing wrong. Thanks.
  24. I am having some performance issues with collision groups on mobile. I have 13 enemy sprites in game that collide with map polygon boundaries. Having the enemy sprites in game degrades the fps from 60fps down to 30fps. As I reduce the number of enemies in game the fps increases. 13 seems like a really small number of sprites to have in game so I feel like I must be setting up the collision detection incorrectly. I am trying to setup a base map with polygons to use for collision boundaries of the map. I want to have enemies go back and forth horizontally between the map boundaries. They w
