AndEngine: Handling collisions with TMX Objects

Question

I managed to load a tmx map now I would like to create the obstacle that the sprite can not move, I recovered the obstacle like this :

try {
        final TMXLoader tmxLoader = new TMXLoader(this, this.mEngine.getTextureManager(), TextureOptions.BILINEAR_PREMULTIPLYALPHA, new ITMXTilePropertiesListener() {
            @Override
            public void onTMXTileWithPropertiesCreated(final TMXTiledMap pTMXTiledMap, final TMXLayer pTMXLayer, final TMXTile pTMXTile, final TMXProperties<TMXTileProperty> pTMXTileProperties) {
                /* We are going to count the tiles that have the property "cactus=true" set. */
                if(pTMXTileProperties.containsTMXProperty("obstacle", "true")) {
                    //TMXTiledMapExample.this.mCactusCount++;
                    //coffins[coffinPtr++] = pTMXTile.getTileRow() * 15 + pTMXTile.getTileColumn();

                }
            }
        });

How do I handle collisions with obstacles so as to prevent the player from walking through the obstacle (i.e., like a wall)?

Answer 1

since I use this

if(pTMXTileProperties.containsTMXProperty("obstacle", "true")) {
                    //TMXTiledMapExample.this.mCactusCount++;
                    //coffins[coffinPtr++] = pTMXTile.getTileRow() * 15 + pTMXTile.getTileColumn();
                    //initRacetrackBorders2();
                     // This is our "wall" layer. Create the boxes from it
                        final Rectangle rect = new Rectangle(pTMXTile.getTileX()+10, pTMXTile.getTileY(),14, 14);
                        final FixtureDef boxFixtureDef = PhysicsFactory.createFixtureDef(0, 0, 1f);
                        PhysicsFactory.createBoxBody(mPhysicsWorld, rect, BodyType.StaticBody, boxFixtureDef);
                        rect.setVisible(false);
                        mScene.attachChild(rect);
                }

Have fun !
