  • I did some tests and the results are interested. Displaying 2048 random 2-digit numbers on every tick:

    • A single text object - 3 fps
    • A single text object with bbcode (random color for each number) - 15 fps
    • A single spritefont object - 144 fps, 25% cpu
    • A single spritefont object with bbcode - 30 fps, 100% cpu
    • 2048 separate text objects - 5 fps
    • 2048 separate spritefont objects - 75 fps, 70% cpu

    For some reason text is rendered slightly faster when it has lots of bbcode tags. And the winner is a single spritefont, it's massively faster, but it doesn't like bbcode.

    Since you only need to display 16 characters, you can add highlighted versions of them to the spritefont image and update the character set in spritefont properties. This way you can display white or red numbers without using bbcode.

  • Like I said, ask your questions on the forum. There is also a very active Discord server:

    discord.gg/Z6jjNQys

    And of course you should study tutorials and official examples - it's the best way to learn Construct.

  • But opacity=0 is not the same as visibility. It's not possible to check visibility in an expression. There is a silly limitation in Construct that expressions can't return boolean result - visible/invisible, enabled/disabled etc.

  • Spline is a simple behavior. Add points one by one, and the sprite will move from point to point.

    If you have any questions, ask them here - this is what the forum is for.

  • I've been getting inconsistent results using the second method. Sometimes the colour looks completely different like in the screenshot below, where red displays as blue. Could you explain why this happens?

    You can't use online tools. C3 uses some custom formula for colors, so you need to convert r+g+b values with rgb() expression. Make a little project with 3 text inputs and a button.

  • Color data consists of 3 values. So if you want to store them in one cell, you will have to store them as a string of text. For example "255,0,255" (but without the quotation marks). And then separate them into 3 numbers for rbg() expression:

    Set colorVar to Array.at(0,2)

    Sprite set color to rgb(int(tokenat(colorVar,0,",")), int(tokenat(colorVar,1,",")), int(tokenat(colorVar,2,",")))

    .

    Another option is to pre-calculate all color values. For example, rgb(255,0,255) returns number 16711935. So you can store it in the array and use directly in "Set color" action, without the rgb expression.

  • 2048 text objects all displaying 2 characters each

    Text objects are rendered on the canvas, and updating so many of them on every tick is not a great idea. Can you compose a single string and display them all as one large Text or SpriteFont object? Using a monospaced font of course. It should work a lot faster than 2048 separate texts.

    I would probably use a combination of Javascript and events - a script to generate that string and events to display it.

  • I don't have rex's demo, but here is mine

  • What exactly is your question?

  • how do you open the project in an older version

    Unpack c3p file into a folder. Open project.c3proj file in any text editor and update this string:

    "savedWithRelease": 39700

  • You mean you use "Add animation frame" action, and then load an image into it?

    Yeah, there really should be an action to set origin point for the added frame. Please vote for this suggestion:

    github.com/Scirra/Construct-feature-requests/issues/246

  • You can add several empty frames in the editor, with different origin point positions. Then in runtime select a frame with the desired origin point position and load your image.
