New this build: collision polygons and global objects!

Collision polygons allow you to make a shape around an object which is the area it collides with. This means objects can collide more realistically than the "bounding box" method before. You can edit collision polygons in the image editor, as shown:

Release 57 collision polygons

As you can see, you have the option to set the bounding box like it was before (which is faster). You can also get Construct 2 to guess the collision polygon. It can't read your mind so it'll never get it exactly perfect, but it gives you a good starting point to tweak and get the collision polygon you want, which helps save time.

Note existing projects opened in r57 will still use bounding box collisions. You'll need to manually 'guess' or edit the polygons to change it. However, new projects started from r57 will automatically guess polygons for imported images.

Be careful with collision polygons - if you add too many points it can make the game run slowly! Construct 2 warns you if you add more than 8 points, which should be OK for most objects. We've also updated the Space Blaster demo to use collision polygons, which actually improves the gameplay (no getting hit on your spaceship's bounding box corner!)

Global objects are pretty straightforward. They simply don't get destroyed at the end of the layout, and continue to exist in the next layout. You can make objects global via the properties bar.

That's all for now, more on the way!

Changelog

Feature

Collision polygons. Can be edited in Sprite's image editor.

Feature

Global objects. This allows you to have sprites, arrays and other objects last between layouts. ('Global' pretty much just means 'don't destroy at end of layout'.)

Bug Fix

'Undo' after editing the origin or image points now works correctly

Bug Fix

Renaming objects could cause invalid expressions in some rare cases

Bug Fix

Check failure entering an expression consisting only of whitespace

Bug Fix

Possible crash hitting Ctrl+S (save) while dragging objects in the layout view

Bug Fix

Possible crash selecting back then next on instance variable parameters

Bug Fix

Triggers may have worked incorrectly in some cases

Congrats on getting the investment! :)

I am super excited about these developments. You are doing things I have been begging that other company to do for years. You have all of my support.

Just installed r56 :P

Awesome addition! At first I thought I wouldn't need the poly. collisions but I guess it will come in handy.

I was wondering - What's best for performance: A invisible collision rectangular sprite, or creating a collision polygon?

Thanks in advance! Keep up the (as always) great work!

It's not much difference. A rectangular sprite basically has a four-point collision polygon (the four corners of the rectangle). Still, 5-8 poly points shouldn't be much slower than four.

Collision polygons will make it some much easier to implement games. Much appreciated!

@Bobwaite we can't say for sure at this stage how long early adopter prices will be available for, but we do promise to give fair notice before changing it! I'd say you're safe for a while yet anyway.

Exactly what I needed for my current project, thanks!
This was probably ranked no. 2 on my wishlist for things to be implemented early on (families being no. 1)

Loving this steady flow of updates. I'm all giddy, looking forward to the next ones!

I was picking my jaw from the ground where it felt before writing this little comment.
Polygon collision (and global object) arrived a hell sooner than I thought it would.

Careful Ashley, you're giving your community bad habits, we will soon be ranting when a week goes by and no new release shows up [;)]

Just wanna to say I am starting to get very impressed with yer dedication. Today I have "adopted" a license, you have my support . Where's the place to suggest features?

Weird my badge is not showing. Could it be cos my PayPal email is different than the one I signed here up with?
