    First of all, why are you multiplying the angle of movement by 2? Angle and speed are completely different things. Angle could be 0 and speed could be 1000, you can't derive one from another.

    Second, applying force correctly may be difficult and it will set the ship off-course.

    I suggest you use angular velocity - it only rotates the ship without changing its direction of movement.

    You can still animate ship reactors (thrusters) if you want.

  • 1. Watch more tutorials online.

    Personally, I don't understand everyone's obsession with youtube tutorials. Yes, they are often helpful and people who record them are heroes. But it's such a waste of time - watching a 10-20 minute video while reading the same tutorial would only take a couple of minutes. Even if I skip to the end, I often have to return to random parts of the video trying to find the pieces of information I need. Ugh...

  • Actually, I was not technically correct in my previous comment.

    Yes, "&" is used to concatenate strings, but this is also a logical "AND" which can be used in math formulas

    For example:

    newHealth = health- (armor<1 & shield<1)

  • Try this:

    "HIGH: " & (HighLevelStart-DropLossHigh-SplitterLoss)

    & is a concatenation symbol, used to attach two strings together. You should not use it in math formulas.

  • Then, like I said, you'll need to perform a ton of overlapping checks to determine object shape.

    If this can be done easier with Trace plugin, you should definitely use it.

  • Nice question!

    Here are my thoughts:

    1. Give yourself challenging tasks, you can find lots of these in "How do I.." forum.

    2. Study other people's code, but keep in mind that it's not always good or correct (especially in "How do I.." forum ). You can usually recognize a good code if it's well formatted, commented, functions/loops/groups are being used, variables and objects have meaningful names etc.

    3. Explore expressions - every object in C2 has dozens of useful expressions and many people have no idea about them.

    4. Read this post - Best practices in C2

  • See this post:

  • There are several C2 plugins for seeded random. I don't know if any of them ported to C3.

  • Try Construct 3

  • Here is another way to smoothly rotate a sprite 360 degrees in 1 second.

    Using "dt" guarantees constant speed even if the frame rate changes.

  • Yeah, TextBox "intercepts" most keyboard events. I think "On Return" and "On Escape pressed" are the only ones that work inside the text box.

    Thanks!

  • Are you using TextBox?

    You can use "Keyboard -> On Return pressed", this event triggers even when cursor is inside the textbox.

    I've just tested, it works on mobile with on-screen keyboard.

    Thanks for the coffee! : )

  • In your capx you made every bullet harmless for 5 seconds.. Which is wrong, obviously.

    For this task it's best to use Timer.

    Add isImmune boolean instance variable to your Player sprite and Timer behavior.

    Change your code like this:

    (clickable)

  • Oh, sorry, I misread your previous comment.

    You need to add "Set bullet speed=1000" after "Set Bullet enabled". This will reset the speed.

  • You can request fullscreen only after a touch or mouse event.

    For example "On tap -> Browser request fullscreen"

    Note, that you can't do it in "On touch start", it will not work in some mobile browsers. Better use "On Tap" or "On touch end" or wait 1 frame after "On touch start".

  • Yeah, angles in C2 can be confusing. Say, angles -30, 330 and 690 are actually the same angle.

    If you use system expressions anglediff, anglelerp, anglerotate etc. - they take care of conversions for you.

    For example anglediff(-29, 690) = 1

    If you still can't fix it, please share your capx or a screenshot of your code.
