  • TileMap object has a number of expressions to convert tile coordinates to screen coordinates and vice-versa.

    PositionToTileX(x)

    PositionToTileY(y)

    SnapX(x)

    SnapY(y)

    TileToPositionX(x)

    TileToPositionY(y)

    Use TileAt(x,y) to get tile ID.

    As for your second question, it depends on your game. If this is just for storing customizable properties for individual tiles, I would probably use an array or dictionary. If you need to add animations, behaviors etc. to your tiles, you will need to replace them with sprites. (or put sprites on top of them)

    I have an event set up so when I click the tilemap in an editor window (separate layer, paralax 0,0), but it selects tile id -1 instead of the tile I clicked on. I'm assuming it's not translating the mouse coordinates to the editor tilemap because of the parallax (the tilemap technically isn't moving)..

    Not sure I understand.. You may need to add scrollx, scrolly to your mouse coordinates. And probably subtract WindowWidth/2, WindowHeight/2. It's hard to tell without seeing your capx.

  • Use "Overlapping at offset" or compare distance(sprteA.x, spriteA.y, spriteB.x, spriteB.y) using "System->Compare two values"

  • You can try spawning two light sprites.

    One with "Destination out" blend mode to make a hole in dark layer. And one with something like additive blend mode or overlay effect on the background layer to add color.

    There may be a better way, but I couldn't find it.

  • Here is the method I know:

    https://www.dropbox.com/s/dcpe4ksor5uv7 ... .capx?dl=0

    Also, there is an example project in C2 - start a new project and select template "Multiple colored shadow casting lights"

  • In events where several object instances can be affected (like bullet collides with two enemies) I prefer to add another sub-event "For each Enemy". This often helps to prevent some weird and hard-to-detect bugs.

    Or if you need to make sure that each bullet should wound/kill only one instance of enemy, add "System->Pick random Enemy instance" as a sub-event.

  • Touch-> On any touch start :  SpawnPointSprite -> Spawn another object -> BulletSprite
                              BulletSprite -> Set angle toward position-> (Touch.X  , Touch.Y)
[/code:1r7sqxi1]

Also make sure that you have "Set angle=Yes" in Bullet behavior properties.

  • "trigger once if true" should work, you are probably not using it properly.

    You can do this without the "areaclear" variable:

    Enemy-> Is boolean variable Dead set 
      System->Compare two values -> Enemy.pickedCound>=10  :  Go to next level
[/code:yp3rty5g]

First event will pick all dead enemies.
Second sub-event will compare number of picked instances.

  • First issue - change your event to this:

    if Enemy has LineOfSight to player -> Set Enemy angle to Anglelerp(Enemy.Angle, angle(Enemy.X, Enemy.Y, Player.X,Player.Y), dt*4)

    Number "4" here is the speed of rotation.

    Second issue - after 1 second you can move your enemy to this position:

    MoveTo ->

    X=Player.X + choose(-1,1)*random(20,50)

    Y=Player.Y + choose(-1,1)*random(20,50)

    This will simply move the enemy to a random point around the player within 50px, but not closer than 20px.

    Or, if MoveTo behavior has "Move at angle" action, you can do something like this:

    Set dist=distance(Enemy.X, Enemy.Y, Player.X,Player.Y)*random(0.2,0.5)

    Move (dist) at Angle (angle(Enemy.X, Enemy.Y, Player.X,Player.Y) + choose(-1,1)*random(30,60))

    These formulas are just off top of my head, may not work very well.

  • Sure, just add a global variable JumpEnabled=0

    On Key pressed "Space" change this variable to 1

    Add a second condition to your "player > platform is on floor > player > Simulate platform pressing jump" event:

    System->Compare global variable-> JumpEnabled=1

    (to add another condition, select this event and press "C")

    If you can't open the capx, rename it to .zip, unzip to an empty folder, open .caproj file in Notepad and edit this line:

        <saved-with-version>24700</saved-with-version>

For example change to:
    <saved-with-version>24400</saved-with-version>
[/code:1dq0e90q]

Then open it normally in C2.

To speed up objects in C2 you can use System->Set Object Time Scale. This will speed up (or slow down) everything related to this object - animation, timers etc.

  • NECRONOMICRON

    It's a completely different kind of game. The light ray is moving (growing) slowly and you need to place mirrors on its path. And all this in isometric projection.

  • Please reload the capx, I made some more changes.

  • You really need to read a few tutorials and look at some examples of other people's projects.

    This will save you a lot of time!

    You should not create dozens of identical sprites! This is the biggest and most serious problem with your project. Don't do this!

    Create just one sprite and make lots of its instances.

    Learn to use instance variables.

    Learn to use functions.

    Define correct collision polygons and image points in your sprites.

    I fixed some of these issues in your project and optimized your code a lot.

    As for the ray reflection, it still needs some work, I didn't have time to finish it. See my comments in the event sheet.

    I don't think Light plugin can be used in this game, so I removed it.

    What's "H5"?

    I haven't tried this, but there are 2 plugins to convert images to/from string (which you can save in local storage):
