Thank you both for your replies.

I've been tinkering around with physics and it seems that if your character is travelling right and hits something whilst you're still holding down the right key, you don't bounce. It's like the holding of the right key overrides the bounce action. I've tried momentarily turning off the 8Direction upon collision but it produces very haphazard results.

I tried Bullet motion for moving the character, leaving 8Direction completely alone, and that seems to work. The only difficulty is if you want to change the speed of the character you need to change the density and linear damping to avoid some very wacky results. It's a shame that my game requires a high number of speed changes!! <img src="smileys/smiley5.gif" border="0" align="middle" />

I think this is going to take a lot more testing. If you have any more ideas I'd be most appreciative, though!!

Hello all.

I have a round-shaped main character who is in a top down game. There are other round-shaped NPCs in the game, NPCs who move. When the main character and the NPCs collide I wish to have them both bounce away from each other.

In order to try to make this happen I have tried the following...

Given both of them physics and tried adjusting the elasticity and density of the objects.

Created an event where upon collision an impulse tries to push the player away from the impact.

With everything I've tried, the main character just pushes through the NPC with no real impeding of its movement, or the NPCs get thrown away violently.

Am I missing something? Is there any way to do this?

That's a really good article. I didn't find that. Thank you for linking it!!

I have one last question. If you use the same sprite to tile the entire background but you use different animation frames at each location, does the game consider it to be a single sprite or as many sprites as there are different animation frames?

The tutorial linked below shows that the platforms are all the same sprite but they have different animation frames.

Please forgive me for bumping my own post but if someone does know the answer I can spend my Sunday making my backgrounds!!

(Crosses fingers, hoping someone more knowledgeable than me knows the answer...)

Hello all.

I'm looking to make a top scrolling shooter for the iPad and am wanting to use a tiled background as it will save me an immense amount of time creating the maps.

The tutorial below states that less than 20 sprites should be used in order to maximise performance. Does each tile count as a sprite or will the fact that the tiles are doing nothing exempt them from this 20 sprite guideline? The tiles are of a size that there will be around 30-40 of them on screen at a time.

Thanking you in advance!!

Hello all.

I'm a new user (previously a GameSalad user) but I got a little tired of some of GameSalad's deficiencies, most notably the lack of adequate pathfinding. I've spent all day today going through the tutorials and am really enjoying Construct 2. I have a couple of questions, though.

My end goal is to publish games on the iOS app store, but after searching and reading the forums I still have some gaps in my knowledge. I'm really hoping someone can help me with a couple of answers.

Is there a cost to using Intel XDK? The Intel XDK tutorial was written in 2012 and doesn't mention any costs to using the service. Additionally I cannot find anything on the Intel XDK site in regards to cost.

A post written in 2012 stated that PhoneGap has issues with sounds. Has this been rectified?

Lastly, has anyone published to the iOS app store recently? If so, what was the cost (excluding the Apple Developer cost) and was your experience a good one? Also, what do people think to be the cheapest way to publish iOS games that are fully functional? (I know I sound cheap but I'm a hobbyist and have a budget.)

Any help would be greatly appreciated!!
