  • WebGL Effects would be easier to use if you were able to read in "Set Effect parameter" the name of the parameter you are changing.

    You can read the name by browsing the Effect xml file, but I find very odd to force programmers to define parameter names and then don't use parameter names at all in C2. I guess parameter names are used in Construct classic.

  • Do you think I could use your plugin to do a movement detection (i.e. getting sprite1 from camera, getting sprite2 from camera, pasting blue into Alpha, and then xor-blending sprite 1 and sprite 2? I tried to do that with webgl effects -- but they are applied only on video memory and resulting images are not accesible for canvas.

  • Hi!

    I was trying to make a simple webcam motion detection app by loading sprites with usermedia snapshots at set intervals, and then calculating the difference between them with a "difference" effect.

    My idea was to load the resulting image into a canvas object (using the canvas plugin by R0J0hound), so I can do pixel-color based collision detection.

    But when I paste sprites into the canvas object, effects are lost.

    I don't want to use the "Snapshot canvas" System action, because it saves the image from all layers. Any Idea?

    Might I use two different canvas objects and manually calculate the difference?

  • I'm doing that and runs better in that order, but still repeating sometimes (i.e. picking instances without the right instance variable).

    Is there a way to detect if there is no instance with the right variable at all? i.e., can I count the result of a "compare instance variable"?

    If I can't, then I'll add a counter to detect if all instances have the variable already set.

  • Hi!

    I wonder if I can combine the "Pick random instance" with the "Compare instance variable". I'm making a Geography quiz using sprites as questions, and I would like to choose a random sprite from the un-answered ones.

    In my test project I see that a mere combination of "Pick random instance" and "Compare instance variable" in same event does not work. Do you think putting one or the other as sub-event would work?

  • Many thanks to all.

    I like your tiny cards, telles0808. Where did you get them from? Mine are from SVG-cards 1.01, that are good for high resolution, but render poorly at low resolution.

  • I'm using array objects indeed. I forgot they are called "array" (not matrix) in computing.

  • Consider a smaller/simpler "Loading" layout. In my browser, I have to wait 30 seconds before I see the "Loading" message.

    (Maybe it has something to do with game being stored at dropbox)

  • Try Construct 3

  • Game plays fine in my browser, but it is a Chrome with a big screen (1600x900).

    As for same first-letter words, could you select the word in the FASTER zombie, instead of selecting thw word in the FIRST zombie?

  • Hi!

    I'm trying to make a simple card solitaire/patience game.

    I created a sprite called 'Card' with instance variables to store suit, number, stack/column, and position inside stack.

    Stacks are stored in two matrices: a 2D matrix containing indices to the cards, and a 1D matrix containing pointers with the number of cards in each stack or column.

    But if I store indices to the cards as UIDs, I find no card when I use Card object condition 'select object by UID', and, if I store indices as IIDs, I always find same card object (Card #0) when I use System object condition 'Select object Card with index X'

    You can take a look at my project at:

    here (10 Mb download)

    Beware it is a 10Mb download, since it contains all images for the cards (they are needed to understand it).

    (If you finally download it, you'll find useful to know the meaning of these Spanish words: Carta=>Card, Palo=>Suit, Numero=>Number, Mazo=>Stack, Columna=>Column, Fila=>Row).

  • I was using r99. I think this could be caused by zooming, as julmust says.

    Here is my last discovery:

    Everything is allright in an exported website (where everithing is smaller), while problem persists at preview. That's funny since I'm using the same browser for preview...
