Cool deal bit…
I see you understood the concept of those grey boxes then? Or did you use something different for that?
Yeah… The finished layout of mine will be at around 550 x 450… I just amde it smaller so I wouldn’t have to mess around with too many things… Expanding it to a larger size isn’t going to be hard and neither is putting everything into mation and stuff…
I already helped someone out with the shooting algorithms and stuff like that… I can just copy and paste my own code to use in it 🙂
Take it easy man,
btw… If you gte the chance… I’d love to ask you if you could help me come to a conclusion about this isometric design concept I’m having… For collision detetction in it…
Thanks Again

actually, i didn’t use any extra boxes or anything. i just drew the shape in an empty movie clip, then did a hit test against the “bomb’s” position. then did some math to find out where it hit and what point to move down.

Nice job, Playamarz 🙂

Yeah… I see…
Hmm… Doesn’t .hitTest do the boundry boxes? Or did you do a hitTest against the general location of all the points inside of the movie land clip?
I would check out the .fla but I don’t have flahs on this computer… My truck’s brakes went out… SHIBBY! hehehe…
Peace

i draw the shape inside a movie clip called “land”
then i can do a hitTest like:
land.hitTest(bomb.\_x, bomb.\_y, true)
this sets the shapeflag to true, which checks the actual shape, not bounding box.

OH SHIBBY!
No fake?!?!
d00d… Thanks for informing me for that now… GEEEZZZ
_lol_… That’s cool though… I can decrease the code of this for a while…
Peace Out

When testing for the true shape, and not just the bounding box, doesn’t that make the movie more processor intensive? Just a word of caution…
Nice job Playamarz 🙂

Nice trick, Bit. 🙂 And Jubby, I have no idea. But you can test the speed of both commands very easily with a timer if you really want to know.
pom :crazy:

heh, this is at bit-101’s lab section too 😛
one of the newest additions 😏

Yeah…
I inspired him to recreate it…

Actually… When you think about it…
It couldn’t be too much mroe intensive than say…
20 hitTests on those grey boxes… And when expanding to a wider movie… At 650 pixels with 10 pixel intervals… That’s 65 hitTest / frame…
That’s gotta be slower than one trueform hitTest… Wouldn’t you say… Thanks for the tip bit.
Peace
