  • Yes, you can select all events and press "R".

    The objects you are replacing should have the same instance variables, behaviors etc.

    .

    There is a big chance that what you are doing can be done much easier and more effectively with families. When you have to copy-paste the same code for different objects, it's almost always can be optimized with families.

  • That "E_Config_something" - is it some object, like a sprite, with Health instance variable?

    .

    Unfortunately, what you are trying to do is not possible. You can't refer to objects or variables using their string names.

    If you give more details about what you are trying to achieve, I may be able to tell you how it could be done better.

  • That said, I have no idea how or why this suggestion could have gotten 106 votes in just a few days

    Yeah, it got me puzzled too :)

    .

    I would probably like to see a different feature implemented - a Global Event List. When you mark an event list as Global and it becomes "visible" from all other event lists, without the need to include it. Would be useful for generic events and functions.

    EDIT: Event Sheet, not Event List, sorry.

  • Like I said, you have logical errors in your code. In events 5 and 6 you are changing animation without updating the Ball variable. That's why when you press Z after that, the variable changes, but the animation doesn't.

  • You can use "Between values" condition:

    tilesMap.TileAt(tilesMap.PositionToTileX(player.X), tilesMap.PositionToTileY(player.Y)) Between 60 and 64

    .

    You can use the "|" operator like this: 

    Set variable tempTile=tilesMap.TileAt(tilesMap.PositionToTileX(player.X), tilesMap.PositionToTileY(player.Y))
System compare two values: (tempTile=60 | tempTile=61 | tempTile=62 | tempTile=63 | tempTile=64) EQUALS 1

  • You can keep these values somewhere else in your C2 project and pass them to JS function as parameters. Something like this:

    Browser execute JavaScript "yourJSFunction('" & serverName & "');"

  • Yes, you can call back a function in C2 using this code from JS:

    c2_callFunction("FunctionName", [return_value]);

    .

    Here is a demo:

    dropbox.com/s/f9vte9290eidvm6/JS_Callback.capx

  • Please post your capx or at least a screeshot of your events.

  • I didn't notice the attached file, sorry.

  • The Function_Advanced is fully compatible, just not available.

    It's a very simple plugin, yet a masterpiece.

    [...]

    If it were, we could have done it on Construct 2 long ago.

    What are you talking about? What function_advanced, what plugin?

    Does a plugin that allows calling functions from another event sheet already exist in C2?

  • I know they look and sound scary - AJAX, JSON, ARRAYS, OMG!! - but they are really not!

    Just start using them and you'll see. Download a few examples from the tutorials section, try changing some bits. You only need two or three lines of code to load something with AJAX, you don't even have to understand how it works, just copy them from someone else's project.

    Same with JSON - all you need is Array.AsJSON expression to convert array to string, and "Array load from JSON" to convert it back. Two lines of code! Again, you don't need to know anything about JSON, its format, structure etc.

    .

    You can save individual variables to Local Storage if you wish. But to save/load 20 variables you will need like 60 events!

    To save/load an array or dictionary with the same 20 values, you will only need 3 events. See what I mean?

  • This could happen on some keyboards if you press 3 or more keys at once.

    If this is not the case, then there is probably something wrong with your code, please share your project file.

  • I still think you are wrong.

    You are basically asking to implement a hack.

    I can see how this feature can be useful in some projects, but I also see how many people (especially beginners) will abuse it and this will result in very poor code organization, and could potentially cause more harm than good.

  • There is a number of expressions you can use to convert from layout coordinates to tilemap x,y:

    PositionToTileX(x)

    PositionToTileY(y)

    Convert an X or Y layout co-ordinate in to the corresponding tile number in the tilemap. For example, this can be used to get the tile position under the mouse.

    SnapX(x)

    SnapY(y)

    Snap an X or Y layout co-ordinate to the nearest tile. This also returns a layout co-ordinate, but aligned to the nearest tile in the tilemap.

    TileAt(x, y)

    Return the tile ID at a position in the tilemap. Note the position is given in tiles, not layout co-ordinates. If the tile at the given position is empty (has been erased), the expression returns -1.

    TileToPositionX(x)

    TileToPositionY(y)

    Convert a tile position to layout co-ordinates. For example, this can be used to position a Sprite object on top of a given tile.

    .

    So you can get tile number that player is on using this formula:

    tilesMap.TileAt(tilesMap.PositionToTileX(player.X), tilesMap.PositionToTileY(player.Y))

    You can check 4 points at some offset from the player to prevent it from stepping into water etc.

    .

    Creating a separate invisible solid tilemap for collision detection is actually a very good and popular solution. It will not make your project file any larger, because you only need one tile (just a black square).

    You can auto-generate this collision tilemap based on tiles on your main tilemap. Just loop through all x,y tiles on your main tilemap and set or erase corresponding tiles on the collision tilemap.

    When your player is in "walking" mode, erase entire collision tilemap and then set tiles with water, trees, mountains etc. When your player is in "boat" mode, set tiles for the entire collision tilemap, and then erase water tiles.
