  • Try this:

    Every tick -> BulletSprite set Angle to anglelerp(Self.Angle, angle(Self.X, Self.Y, Target.X, Target.Y), dt*4)

    In Bullet behavior set "Set angle=Yes"

  • What you probably looking for is Else condition.

    If condition A -> action A

    else -> action B

    You can also use other conditions after Else:

    If condition A -> action A

    else if condition B -> action B

    else if condition C -> action C

    else -> action D

    "Else" can't be used with triggered events like "On created" event on your screenshot.

    Triggered events have a little green arrow and usually start with "On.."

    You can see the list of all expression in the expression editor, there is a semi-transparent window with all objects in your project. If you click System for example, you'll find all system expressions.

  • I'm guessing you want to select rotation direction randomly?

    Use choose(0,1) to "flip a coin".

    if choose(0,1)=1 then rotate clockwise

    else rotate counterclockwise

    Or you can use choose() expression in a formula: Rotate (choose(-1,1)*degrees)

  • If I understand you correctly, you can try this:

  • RBARON85

    You have to do this in 2 steps:

    Step 1. Pick an instance of the sprite.

    You can use any method to pick an instance:

    Sprite->Pick by unique ID - if you know the UID

    System->Pick random - if you want a random instance

    Sprite->Pick nearest/furthest

    etc.

    Step 2. Move to (Sprite.X, Sprite.Y) position.

    Again, there are plenty of ways to do this. The easiest is MoveTo behavior, or you can use Bullet, LiteTween or simply move your object a couple of pixels towards (Sprite.X, Sprite.Y) on every tick.

    Note: Step 2 should be a sub-event to step 1.

  • Maybe just restart the animation after it has ended?

    Character->On Finished "Speak" Animation -> Character play "Speak" animation

  • facecrime

    No, see my code - you can calculate (time-ButtonSprite.timePressed) to fill up the meter while the button is being held in "Is Touching" event. You can add other conditions, say the meter starts filling up if holding time is more than 1 second, and stops after 3 seconds.

    The same formula can be used when touch is released or after finger has moved away from the button - in "Is NOT Touching" event, before resetting timePressed to 0.

    You don't need another flag, since you have timePressed variable. When it's 0, you know that the button is not in touch.

  • You can try something like this:

    Add an instance variable timePressed to the button sprite.

    Create these events:

    Touch: On touched object ButtonSprite -> ButtonSprite set variable timePressed to (time)

Touch: Is touching object ButtonSprite  
ButtonSprite: compare variable timePressed not equal 0
                                     // use formula (time-ButtonSprite.timePressed) to get the duration of hold

Touch: Is NOT touching object ButtonSprite 
ButtonSprite: compare variable timePressed not equal 0 
System: Trigger once
                                     -> ButtonSprite set variable timePressed to 0
                                    // release the charge based on hold duration

  • Kyatric, As I understand from the Java code, Card[] array contains 10 cards. (1-based for simplicity)

    Cards which user owns contain value "1".

    Cards which user doesn't own contain value "0".

    The task is to select a random card which used doesn't own. Basically find a random member of the array with value ="0".

    This can totally be done in C2 without the array and much easier. Pick all cards with instance variable="0", and then pick a random card from them.

    Here is a slightly more accurate example:

  • You should have posted this in "How do I...?" forum on day two of your quest

    When I have a hard-to-detect problem like this, I start disabling big chunks of the code and adding debug output everywhere. This usually helps to narrow the search scope and find the rogue event really quickly.

  • Do you mean you want to rotate the ship?

    Here is how you get movement angle:

    angle(0,0, Ship.Physics.VelocityX, Ship.Physics.VelocityY)

    You can slowly change ship angle until it reaches this angle, for example:

    Ship -> Set angle to anglelerp(self.Angle, angle(0,0, Self.Physics.VelocityX, Self.Physics.VelocityY), dt/2)

    It's not recommended to change angle for physics objects directly, so you can try to do the same with physics actions like "set angular velocity".

    And, of course you should only adjust the angle when player is not controlling the ship.

  • It's up to you.

    Here are a few tips:

    1. I can drop letters on top of each other.

    Add isOccupied instance variable to your Sprite133 (grey box). Set it to True when letter is dropped to it. Set it to False when letter is dragged from it.

    You can also add instance variables startX and startY to the Letters sprite. On start of the layout, save X and Y position of Letters instances to these variables.

    Then if the letter is dropped on an occupied grey box, return it to (startX, startY) position.

    3. If I pick up letters again after I dropped them, or if I change their order, the Word.text should be recalculated. Currently a letter is just appended at the end, which is wrong.

    You can try something like this:

    Word set text to ""
Sprite133 -> boolean variable isOccupied set   // this will pick all occupied boxes
   For Each Sprite133 order by Sprite133.UID   // This will loop through occupied boxes
       Sprite133 is overlapping Letters   // This will pick a letter on each box
           Word append text  Letters.AnimationName    // and add this letter to Word
[/code:1rsijhor]

You can make this a function and call it every time any letter changes its position.

  • "Letters" sprite is an object.

    When you add copies of "Letters" sprite to the layout, you create its instances.

    For each instance you can select different animation and other properties, set different values for instance variables.

    It's one of the very basic principles in Construct 2.

    All these letters on the layout are different instances of the same Letters sprite.

    To sum up:

    Having 100 letters as 100 different sprite objects is bad.

    Having 100 letters as 1 sprite object with 100 instances is good.
