  • I would treat the spawn area as 4 spawn rectangles. First ceil(random(4)) to pick which rectangle the first object spawns on, then create it (assuming origin point of the spawn rectangle is top left) at spawnrectangle.x+random(spawnrectangle. Width), spawnrectangle.y-random(spawnrectangle.Height)

    For the other object, use layout.Width-object1.x and layout.height-object1.y to get the opposite location. (Or whatever width and height the total black area is, if your layout is bigger.)

    This is slightly less than true random, because the corners will overlap and you have a higher chance of spawning there overall compared to the sides.

  • From the manual:

    [quote:3aq2zl13]Wait

    Wait a number of seconds before continuing on to the next action or sub-events. Other events continue to run in the meantime. See also the tutorial on How to use the System 'Wait' actions.

  • Use the random() expression.

    On SpawnCondition - Set RandomVariable to random(100)

If 0<RandomVariable<30 - Create 30%chanceLootSprite at InvisibleSprite.X+random(-InvisibleSprite.width/2,InvisibleSprite.width/2),InvisibleSprite.Y+random(-InvisibleSprite.Height/2,InvisibleSprite.Height/2)

If 30<RandomVariable<100 - Create 70%chanceLootSprite at InvisibleSprite.X+random(-InvisibleSprite.width/2,InvisibleSprite.width/2),InvisibleSprite.Y+random(-InvisibleSprite.Height/2,InvisibleSprite.Height/2)[/code:1x62l5ug]

Repeat for however much loot you want to create.

  • So... what is your problem?

  • The problem is in your load target.

    You did nwjs.AppFolder&"data/mydog.png" , Windows uses \ for directories, so it should be nwjs.AppFolder&"data\mydog.png".

    To debug, I recommend adding 

    On Layout Start - Set Textbox Text to nwjs.AppFolder&"data\mydog.png"[/code:257wngew] to make sure you have the exact file path correct.

The saving image is as R0J0 described (with small modification)

On click
--- set viewport size to sprite.width, sprite.height
--- scroll to sprite
--- snapshot canvas as jpeg

On snapshot
--- wait 0
--- browser: invoke download snapshoturl

Make sure your textbox overlaps the sprite or it will get cut off.

  • All you need to do is make a second set of controls that do.... something.

    Your requirement is vague.

  • Use an expression - random(x) gives you a random number between 0 and x.

  • A popular option is dropbox.com

  • A capx would be useful to help troubleshoot your problem.

  • I see it stuck on my system as well. Have you confirmed when you load the same project with 216 it works fine? Try downgrading and exporting again. Maybe it is a bug you found, try on the bug forum.

  • Again, how are your roads being created/placed? For example if it is like tetris where a player gets a random piece of road to put down, that distance could be already associated with that piece of road as an instance variable. Or you can use sprite width/height. Or you can calculate pixel distance with imagepoints. Depends on your project.

    Edit/Disclaimer: I'm no expert on pathfinding, so if anyone knows better please chime in

    You can search online for pathfinding algorithms, it is a VERY common problem in the history of programming and well documented as well.

  • Experiment a bit first! You'll be surprised at how far you can get with 100 events.

    Generally speaking, most people do run into performance issues sooner or later, but nearly all of these problems have to do with how they set up their code (loops) and how they make use of their graphics in terms of resources/memory (too many/large sprites and objects). It is rare for projects to get to the scale where the chrome wrapper will make a noticeable difference in performance.

  • I think R0J0 answered pretty clearly in the Paster thread, it definitely is possible even without plugins.

    Which part exactly are you having trouble with? Do you have a .capx you can upload so we can see what you've gotten so far and help troubleshoot?

  • I think you're in the very advanced problem zone =P

    How are your roads placed? Are there constraints like do they need to be connected at ends only, is there a limit to how many roads per intersection?

    When you create an intersection, you'll need some information there including which direction each option is in, and how long that road segment is.

    Basically every time you place a road, you will need to add information at the intersection it was placed on.

    You'll also need to create your own pathfinding - A "simple" pathfinding algorithm would find every possible path to the destination, and compare the total values (length?) of each segment of road to pick the path with the lowest total number. This algorithm should record which road to take at each intersection in a variable or array, which the car then references to make its drive.

    Given that your roads are straight, you can have the car angled at the same angle as the chosen road and have it move forward until it hits another intersection.

  • There are several inventory posts in the FAQ stickied in this forum, as well as a lot of people asking for more specific advice if you search for it..

    There are also quite a few inventory tutorials in the tutorial section.

    Most inventory systems are based on an array. There are many ways to display what is in the array or to change the size of the array.
