Max size is doable by using clamp() on the action in event 4 to set the sprite size. Snapping to sizes in increments of say 32 is also doable with round(width/32)*32. Snapping handles to arbitrary positions would be a lot more complex mathematically.

Do a system compare:

Text.Text = str(int(Text.Text))

I used that site as a reference a while back to make a example in Construct Classic.

To make the preset you could make a utility capx to fill in values in the array then save it to a file with the download action. Add that file to your project and load it with the AJAX object and the array load action.

There are also a few 3rd party plugins that allow loading other file formats such as csv.

I made some some boid examples here:

http://www.scirra.com/forum/boids-tests_topic59833.html

In the third example I used the function object to add all the vector operations and used an array to store all the vectors. I then made any variable be a vector by storing an index of the array, and only modifying the variable with the functions.

If you calculate what the speed will be after applying the impulse, then you can compare the current speed with the calculated speed.

If either of these is true then apply the force:
+calculated speed<max speed +calculated speed>=max speed +calculated speed<current speed

To calculate the speed take the same value used for applying impulse and do this:

vx= self.Physics.VelocityX+IMPULSE/self.Physics.Mass*cos(self.Angle)

vy= self.Physics.VelocityY+IMPULSE/self.Physics.Mass*sin(self.Angle)

calculated speed= distance(0,0,vx,vy)

I made my own capx to figure out a solution so here it is for a working example:

A sprite and an array in a container works for this. Here's an example:

https://www.dropbox.com/s/lipjb22xahgej ... .capx?dl=0

Notice that only two events are used for the recording and playback. The rest are just standard game events.

This idea can be extended by adding some interpolation between recorded states to smooth out hiccups caused by garbage collecting or other programs running in the background.

Paradox
Here's an updated example that positions the handles correctly when rotated.

You can right click anywhere to do rotation and I eliminated the need of an array.

Certainly, you can use it. Most, if not all of the capx I post are free to use.

boolean
Since no picking occurs in your example you can do it with:

System compare (a=b) | ((b=c) & (c=a)) = 1

Here's one example of followers in a platformer. It saves the players position to a queue and positions the first follower to say 10 positions ago, the second 20 and so forth.

Yes, it changes the size of the canvas texture, the image itself is discarded.
