  I did something similar to what you're describing for a top view game:

  This works.

  Set Text to tokenat(replace("1,2,3,4,5,", Text.Text & ",", ""),int(random(4)), ",")

  #This is how you save a object refrence

  System.Create("Sprite", 1, 200,200)

  RefToFirstSprite = SOL.Sprite[0]

  #Then you can destroy it later like so.

  RefToFirstSprite.Destroy()

  You could use the listbox object it specializes in a scrolling list of text.

  If you still want to implement it yourself with events here is a example:

  Here are a few other examples of a scrollbar widgit:

  and here is a uncommented cap of an advanced scrollbar.

  For a smooth transition between colors you can use lerp on each color component.

  If you convert from rgb color to another color space before lerping you can get different results.

  Top down: rgb, ryb, hsl

  Instead of using 3 and 5 in Random(3,5), use two global variables and just set them depending on the level.

  You could use a sprite with a frame per letter.

  Then with events you could do a loop to read each letter eg mid(Text.Text, loopindex, 1).

  Finally once you get a letter you can convert it to a frame number. ex find("abcdefghijklmnopqrstuvwxyz", letter).

  Here is a example I did a while back:

  You could use two sine behaviors with one setting the "period offset" to a quarter of the period.

  Here is an effect that puts a colored outline around a sprite. I does it by offsetting silhouettes of the sprite in eight directions so it can look a bit weird with large line widths.

  Feel free to modify.

  Relevant examples:

  The per pixel collision detection is what takes most of the events in the examples, but it's pretty simple. The canvas object is used to get the opacity of pixels and for drawing a visualization of the terrain.

  Can you make it so the window size is smaller (my max is 1280x900), or move the text objects to the top/left of the layout so they can be read.

  Anyhoo, I changed the window size to 800x600 and all I can read is the "Max Sprite Particles" text. It seems to run fine until it reaches about 1600 and after that the window is not very responsive until it reads about 1700 at which point it crashes to the desktop.

  2nd run crashes at about 1200.

  3rd at about 1266.

  4th at about 1300.

  1. It crashes every time, but you can rule out window size as a cause since it crashes with a smaller window too.

  2. My specs:

  cpu:1.5 ghz intel celron m

  gpu:Mobile Intel(R) 915GM

  3. I couldn't read to fps text (I'll try to move it into view if it's needed).

  Can you give me more of an idea of what the test does? One bug that causes a crash with the physics behavior that has to be worked around is you can only create a certain number (255) of physics objects per tick. It's an arbitrary limit built into the box2d library. If you create any more than 255 physics objects per tick your game will crash to the desktop, so you have to come up with a way to spread the creation over multiple ticks.

  -Happy bug hunting.

  I've tried the physics approach before using a physics rope as a base. I didn't quite get it to have the feel of a cape. I probably didn't tweak it enough though. If you lower the density of the pieces of rope and reduce the gravity it can look close to what you want.

  The only thing that's lacking is for it to catch wind. If the cape were in a complete vacuum it would probably act just like the rope. To do air resistance it might be enough to apply a force 100*sin(anglediff(link angle, angle of motion)) perpendicular to each piece of rope. I haven't tested that but it should simulate more resistance when the rope moves perpendicular to it's angle, and allow free motion when moving the same direction as it's angle.

  This is all a rough idea but hopefully give you some starting points of how to tackle it.

  Use the canvas object, it has a property "grab layout" that if set to "before drawing" takes whatever was drawn under it. You can then apply effects to that area.
