Hello! I'm tryign to design a simple inventory for my platform game with role playing elements. The first thing I faced is that how to collect things in inventory cells? I wrote some events, it works, but I think it is very messy. The logic for this is that array coordinates are the coordinate for cells, and for each sell I have a boolean, than I check if it was overlapped and based on this write events

My project is very big, that's why it is impossible to send it. When I make the position like in examples,(0,0) it works well done, but who needs control keys in this position?) When I change sprite position it doesn't work

Hello! I'm devoloping the game for mobile phone and character control is provided by the sprites (arrows) which I draw. When I make X parallax it works good, but when I made Y parralax it ceased to exist! What can I do with that?

Hello everyone! I'm trying to create the mobile game for IOS and a sufficient part of gameplay is on the picture.

On Iphone 4 I have 17 fps on this scene, on Iphone 5 it is always between 55-60 fps (i am using cocoonjs)

I'm not a programmer, so I don't understand most of things you know and I have some questions.

The first is about Ejecta. Right now I don't have possibilities to test it so if for example I have 17 fps can it be ~30-40 on ejecta or not?

The second is about particles(fire). Fire is a very sufficient part in my game, so it is very painful to reject it. Is there another, more optimised way to implement it in a mobile game?

And the last is from general knowledge. Is it a normal situation that I have now 20 mb memory use (I am using 4 tiled backgounds, ~ 10 sprites, 151 event?

Hello! I make a platform based game for mobile phone and performance is very sufficient.

I heard that we shouldn't create a lot of objects. My game is something which is called handemade, and every sprite has a position I want. And the question is how to make a lot of objects on canvas without slowing fps? Should I determine distance between character and then create object or all objects which are on canvas but not on display don't Make fps lower?

Hello! How can I make a rope in C2, what I need is that my character in a platform game can jump on rope and climbing it to avoid different traps. Animation is not a problem, but how can I make that his hands will be on the rope, and he can properly move?

I give an example from an old good game

Hello! My question is about families. Frankly speaking I haven't design more than one enemy in my games. But nowadays my project is quite bigger and my question is about collision between own object actions and family actions.

For example I have a wolf and a reptile as enemies. And I want a reptile to have special actions during the fight which are collide the family actions. Is it a normal situation or not? Is own object actions cancel the family actions without problems or should i try to avoid such situations?

you could also look at using lerp.

so if you had an instance variable called ivHealth

healthbar set width to lerp(self.width,self.ivHealth,0.01)

Awesome! Thank you very much!

In tutorial we have 100hp and when enemy attacks we then have 95 hp for example and hp bar set width to 95. What I need that it's width should be reducing 100,99,98,97,96,95

True. But there is no solution to my problem. I need hit point bar moving and in tutorial it only depends on value and it is not moving from right to left

Hello! I created the hp bar to show the character hp value and set width to current hp/maxhp*100. It works good but character hp bar reduce its width step by step and what I actually need that it should change its width smoothly moving. How can I do this?

Hello everyone! I'm trying to design a feature in a platform game that when you jump on enemy head you bounce from it (like in Mario).

I tried everything that I can and bullet behaviour did a very good and smooth result but I can't to change it's direction! I tried global values and other stuff but it doesn't works it flies either left or right. Who can help me with that?

For example I make a global variable with bullet direction and set it to -180/180 which is depends on miroring the hero, and than I set bullet angle to this variable but it does not change with the value
