I'm currently working on a top down sprite based game using swift and spritekit, and I'm trying to create a body of water.
I have tiles that transition into water, and some water sprites that i have layered underneath that are animating, but it looks cheap.
I'm wondering if there is a way to generate a body of water using particles or something? I'm fairly new to swift and iOS development in general and this is something i've never done, so i'm just not sure what is possible.
If anybody has any advice or could point me in the right direction that would be great! Thanks.

I have two nodes, player and platfrom. Both have a physicsBody around them. My player is still and the platform scroll by an SkAction. when the player reaches about half-way on top of the platform it falls threw it.
player.physicsBody=SKPhysicsBody(rectangleOf:player.frame.size)
player.physicsBody?.isDynamic=true
player.physicsBody?.allowsRotation=false
player.physicsBody?.affectedByGravity=true
platform.physicsBody=SKPhysicsBody(rectangleOf:platfrom.frame.size)
platform.physicsBody?.isDynamic=false
the platfrom set up is.
plat.size=CGSize(width:(self.frame.width)*2,height:(self.frame.height)/3)
plat.anchorPoint=CGPoint(x:0,y:0)
plat.position=CGPoint(x:0,y:0)
plat.zPosition = 2
addChild(platform)
I tried using this instead but player still falls down
plat.physicsBody=SKPhysicsBody(rectangleOf:CGSize(width:platform.width,
height: platform.frame.height))
I want the nodes to act like a solid object, in that they don't overlap each other when the player moves. Also it there an alternative method I can use. I don't really like working with physics.
An alternate to working with physics is to use the recently added to iOS 10 SKTilemapNode to create the background. Each tile can be tagged with data to indicate if the tile is ground or not. You then focus on how the player moves relative to the tiles. There are currently not a lot of examples to show this working, the WWDC 2016: What's new in SpriteKit shows this briefly. Other resources include a top down example which shows at least how to build the background tilemap and some background info on why physics engines don't provide the best experience for platformers. Kenney's is a good source of tiles for platformer artwork.
I'm making a 2D plane fighting game for the iPhone in cocos2d. I'm trying to make it so when you shoot an enemy plane, it breaks into a couple of separated pieces that will fall out of sight. What is generally the best practice for breaking one sprite up into many? should I create new images for each separate piece, or treat the initial image like a sprite sheet, and make a new sprite from segments?
Please look at this tutorial
It makes a grid of points then moves the internal (not-edge) ones around randomly a bit so it's not all perfect triangles. Then each update it moves/rotates the triangles separately--then draws them all at once.
You treat the whole thing as a sprite, so can run any of the usual actions on it. This example uses CCMoveBy to move the whole group down off the bottom.
Here video link for the Arc puzzle
Can anyone please tell me what concept is used behind this game. I have just started learning Iphone and this game is pretty cool. First I thought it might be using core animation and core graphics. But seeing the movement of the objects it looks much more complicated.
Can anyone tell me what kind of approach do one need to build something like this.
That could very well be Core Animation. You could do the whole thing with CAShapeLayer objects. The code would probably be simplest if each "track/sector" of the arcs puzzle was a separate shape layer.
With a shape layer, if you change the path that defines the shape, as long as the old path and the new path have the same number and type of control points, the change can be animated. Thus, you could animate rotating one of the tracks, (rotation transform around the center point for all track/sector shapes in the track) or animate sliding a track/sector in or out.
I am going to work on a game project. I am using cocos2d. I want to use cccamera class of cocos2d. Please tell me about any tutorial on cccamera. I want to implement more or less like angry birds, throwing the ball that reaches its destination facing the obstacles in the way.
So when the ball moves ahead the scene accordingly moves back depending on speed of the ball.
How to manage all that. I think i should use cccamera.
Thanx.
CCCamera, per the documentation is used for 3D effects (http://www.cocos2d-iphone.org/api-ref/latest-stable/interface_c_c_camera.html) and recommends the use of CCFollow (http://www.cocos2d-iphone.org/api-ref/latest-stable/interface_c_c_follow.html) for 2D related effects (such as following the birds forward, etc).
I am using chipmunk cocos 2d iphone ,in which i have to show stack fall effect when the objects are placed on the edge of other
object.My idea is to develop the effect like "Tower Box " game. I would like to know which properties of shape or body will create effect like "Tower Box " game .please let me know how can I fall that stack.
Cocos2d provides you with a few preset project options.
One of these is Cocos2d with Box2d, another is Cocos2d with Chipmunk. It is completely up to you which physics engine you use, I have experience with both and personally, would recommend Box2d.
If you create one of these projects, it generates some example code for you, and in the case of Box2d (i haven't used an auto generated chipmunk project), you get a nice little app that spawns loads of boxes and shows them falling with gravity. You should take a look at the code behind creating the physics bodies on the boxes and adapt it to suit your application (spawn a box at a touch location, perhaps?). You could then add some logic that checks, on collision, the alignment of the falling box with the top of the stack, and either let it continue falling, or use a fixture to attach it to the box below.
For more information about using physics in a cocos2d app, as well as general cocos2d usage, check out this blog, it's what taught me in the beginning: http://www.raywenderlich.com/ [edit: just noticed there are no chipmunk tutorials on there, but the theory should be applicable to both. I found Box2d easier to use than Chipmunk]
What physics effects have you got on the stack so far? What problem have you encountered that made you question the physics properties of the objects?
For these effects you need a physics library. For 2d games box2d is quite good.
