I've made an example for somebody before.

Take a look at this screenshot and see if that helps your issue:

For your case you will do this 4 times for each side of the box.

While you're dragging the ball outside the box, the ball will stay at a certain y or x depending on what side you are dragging your mouse

You can also use a local variable inside your spawn function and make it a random number between 0 and 1.

If it's a 0 you spawn a tree, if it's a 1 you spawn an animal.

You can make a random number by using "set variable" "round(random(0,1))"

Perhaps you can try the screenshot function built into construct 2.

There's an example file in your program files/construct2/examples

It's called "Taking screenshots.capx"

I can't seem to upload any capx file because it's so called "empty"

Hopefully you can find it in your program files and it is of use to you.

You test it on the platform you want to release it on.

The file wouldn't upload because it's too small so it said it was "empty".

Instead I made a screenshot:

> Try "if RED on collision with BLACK then RED drag_and _drop".

>

The problem is that I wish the black platform slides, the way you say cut the drag & drop

Try to do what he told me TheDom but lost me ...

CompareY: <Les than (457) example. You can explain it again or with an example

You have to add a condition to your drag and drop event that will only apply if your object is between a certain height.

This will cause your object to drop when it isn't in between that certain height.

This however will not slide your object from left to right as it will not be dragging anymore (constantly dropping).

What you can try is to put a condition that whenever you're dragging it beyond a certain Y position, the object will stay on a certain Y level.

I've made a quick example to show you how I've done it:

> You have to make sure every frame and every anchor point.

>

This is not the problem, even non animated sprites appear jumpy

You're going to have to Crtl+F your events and find every event you've added to the sprite that is jumpy to see if anything could have caused it to act like that.

Why do you have the tree and the animal in the same family to begin with?

Events can still be added independantly from each other just as you described by putting "tree.x" this will not affect your animals in any way.

Only events added to the family will be applied to both the animal and the tree.

And if you must know, you could add an instance variable to both the tree and the animal and call it "test".

For the animal "test" will be 1 and for the tree "test" will be 0.

This way you can check the instance variable to see which instant it actually is.

I hope this helps you in the general direction you would like to go.

Can you perhaps take a screenshot of the navigation bar being in the way of your game?

I also believe that letterbox integer scale isn't actually "full screen" but instead just screen filling.

There's some information about full screen in a browser in the manual here:

https://www.scirra.com/manual/110/browser

Perhaps "request full screen" is something that you want to use if you are playing in a browser.

Hope this helped you in the right direction.

You have to make sure every frame and every anchor point (the one used for positioning) are the same size and on the same position.

If they are not, there will be jumpiness as you said in your last post.

Still, my question is why are "real" Boolean types not allowed in "Global" or "Local" variables ?

This seems to be a rather obvious omission, and I'm just wondering if there's an explicit reason.

I personally don't see any benefit from having a Boolean variable compared to a variable that could be anything you'd want.

Conditions can be made like "if false" or "if true" where the variable has either been changed into "false" or "true".

I don't see Booleans adding any functionality that isn't already there.

You can try using the family option.

Hope this helps you in the right direction
