  • Ok i'm need your help guys. i got this arrow above my character ( see image link)

    i need it to rotate around my character in a 180 degree cone.

    Think Bust-a-move you'll see.

    so i try pretty much all my construc knowledge but i'm lost here.

    i create a global variable called "arrow_Ang" and add 5 degree every 1 second.From now on, everything is fine. The problem hit when i want to make it come back when it reach 90 Degree i wish the Global "arrow_Ang" got 5 degree substract and then go back when it reach 270 and so on...

    so i'm blind right now. i try the loop and other thing but i don't know them well so even if its the good tool, i don't know how to make it function well.

    hope i'm clear enough.

  • add "-5"?

  • ??? What do you mean? Something like this?

    Do you want the arrow to rotate too? in that case it's just to paint it in to the circle.

    I really don't know what you mean, so i'm just guessing... anyways. explain further if this didn't help and i'll throw something together.

  • vinny; hehe i tried the add -5... or i did it wrong or construct dont like that

    Attan :what i try to achieve is like the bubble canon in this vid, but over time.

    ie. instead of having the player that orientate the direction its time. a bit like a slow metronome.

    i hopw i'm clearer.

  • Aah! ok, 5min.

    Edit: There you go

  • Sorry im interupting but i made my own example

    3 conditions, 4 events

    Edit: WTF the same name of Variable?

  • Aah, saved some cpu there! now it might not lag so bad!

    i get the last word anyway since it's 3 events, 3 conditions and 4 actions.

    edit: AND he said 180 degree, so you didn't fulfill his wishes!

    FAILURE damn...

    Btw your Every 10ms dont do anything or it does not do much.

  • a bit like a



    I'm fulfilling his wishes

  • I'm fulfilling his wishes

    But it doesn't affect at anything!!

  • Yes it does! it's a little bit slower! not much i thought it would be more, but i exported each version to an exe and ran them an the one with every 10 miliseconds was slower!

    edit: since the framerate is 80 frames per second and 10 milisec is 100 times per second the one with that event will run 1.2 times as fast.

    edit2: DAMMIT! then its FASTER!! self pwnage there...

  • okay okay please don't fight over your CAP lol.

    Both your help is appreciated i learn a lot today.

    So i got another question after this.

    If you look at my screen shot i had a character in it , so the point is, I'm not throwing bubble like bust a move but more make the player jump according to the angle. The arrow is to indicate a jump angle.I use the platform behavior which have the jump th in thing in it but i can't find a way to make it jump at angle without rotating the player.

    now start a duel and fullfil my wishes lol

    I'll post my game soon but i just need to set this part of the game mechanic.

    thanks guys

  • Here's a really simple one using sin.

    For the record, 'Every' can never trigger more often than once a tick. So Every 10ms can run at most every tick - if not, then less often. If you want to run something every tick, use Always, not a small value with Every.

  • Ashley - hell yeah math make things better

    Border - I made example of "Jetpack" Effect, move mouse to change angle of arrow and click left mouse button to activate Thrust.

    Edit: Attan (below) - Yep pretty much beaten

    Edit: Rapidshare link
