Set the origin

I noticed that the x-axis is fine and according to the normal laws of physics, but the y-axis is mirrored.

I'm not sure why, but it is very unexpecteds.

Why is it that the origin is at the top left corner, and y values increase as you move down the screen?

Perhaps there is a setting that can adjust this, I would like to know.

I haven't found anything while searching...

Thanks

you can set the origin to any object by going into the animation settings and on the left side you will see a target that is the origin symbol, you can set multiple origins (known as image points), look at EXAMPLES in start menu they are all there for you to try out.

Thanks for the reply, but that is setting an origin on the object - and is quite easy.

I mean to set the origin for the entire layout.

It feels very un-intuitive to have y-values increasing as positive in what would normally be the negative axis.

There are always ways around this, but now I am more curios to why this has been done.

This is actually pretty common in computer graphics: as an example, that's how Windows itself does it! Another example would be coordinates within the browser window. I expect the original reasoning for this probably relates to how a CRT draws it's image: left-to-right, and top-to-bottom.

It can trip up people who aren't expecting it, but it's no more easy or difficult to work with than the alternative.

Oh, and I'm not aware of any option to use an alternative coordinate system with Construct 2; I wouldn't think it all that likely that adding one would be a priority given how common the system currently in use is either.

Hope the explanation helped satisfy your curiosity. <img src="smileys/smiley1.gif" border="0" align="middle" />

If it helps you visualize, anything after 0 is negative along the xy's.

Also when you think about it scrolling just wouldn't make as much sense if the origin started in the middle.

Come to think of it, web browsers are the same.

Thanks for the help guys :)
