If there's any problems I'd like to know what OS and Browser you use.

I have a very low resolution game (56x32). It runs fine in Chrome for Android on my tablet, but when using Crosswalk the sprite's positions are all messed up. Usually by only once pixel, but this game is low resolution and I'm using pixel rounding so it becomes completely broken.

Here is a screenshot of how it looks in Chrome for Android, the way it is supposed to:

And here is a screenshot of how it looks in Crosswalk:

The entire background seems to have moved up by one pixel, and notice how some of the borders are messed up.

Any way to prevent this?

Oh and if you wanna try the game out yourself, here it is:

Rotating the entire layout seems to cause a really big framerate drop... On my computer it goes down to about 50%! But it does exactly what I was looking for, hopefully I'll be able to make the game more efficient so it works better in this situation.

Wait... I was just testing the Rotate 180� thing and it works perfectly, no need to change any of the behaviors, gravity points up, controls are inverted, etc, I though it only rotated the layers but apparently Construct is that great and does the work for you. Awesome.

I guess rotating by 180� really is what I'm looking for, but doing it that way would mean redefining a lot of the behaviors.

Basically I want to make a split screen layout for tablets, so you can two people playing on the same tablet, on opposite sides, with each side facing each player. Like this game does:

The problem is, my game is a bit more complex than that, and a lot of the behaviors depend on the orientation (gravity, platform movement, etc), so a shader effect would be what I'm looking for, inverting image with a shader would make gravity point up instead of down without having to redefine any behavior.

Right now I could really use a shader that could flip part of the screen. In my specific case, I want to flip the top half of the screen vertically for a 2 player split screen game, so I don't have to configure every behavior differently for each player and flip every single object. Of course there would still be the horizontal flip problem, but it would be a lot easier to deal with.

I was thinking this could be done with a shader. I just want part of the screen to be flipped vertically. Maybe this Construct Classic effect is what I'm looking for:

But I have no idea if there's a way to use it in Construct2.

TL;DR: How do I set the position of an object in relation to another instance of the same object, how do I distinguish them in the action?

In my game, the player character is composed by several objects. Some of them look identical but behave differently. Right now, each part of the character is an individual object, but some of these object share identical sprites, and it would be better to make them all just different instances of the same object.

For example, right now the body's X coordinate is calculated like this:

Body1.X = (Body2.X + Back.X)/2-10

Where Body1 and Body2 are instances of the same object. Should I just keep it as separate objects with the same sprite or is there another way?

Right now it depends on the music playing to actually become playable, which is silly and I'll fix it, but why doesn't it play anything in other browsers like Firefox or Internet Explorer? I searched a bit and it seems Construct 2 is supposed to convert files to two fromats to support most browsers (I used .ogg files made in Audacity), so this shouldn't be a problem, right?

Updated the game, new visuals and some new mechanics.

The body is probably the easiest part in the whole thing. it's just a single image that stretches and positions itself between the head and the butt of the worm. I intend to change it to make the worm's body arch when it moves (making a taller arch when the two parts are closer together and a wider one when they are far apart).

I've updated the game a bit since making this thread btw.

Just a silly idea, obviously the graphics are just placeholders

Any gameplay suggestions? And I'm not adding any more than 2 buttons for each player :)
