whiteheat,

you can also do it like that

scrollingStyles.capx

blockSnapping.capx

as described in the post just before

you create an instance variable named 'name' for slid_line

and you set the value of 'name' for your volume slid_line object to "volume"

+slid_line: name = "volume"
  -> Audio: set "your tag" volume to slid_line.value

if your enemy always go left you can do something like:

You set the maximum speed to 800 or higher in properties

Bullet: On collision with enemy
  -> enemy: Set Platform vector X to 800
Every tick
  -> enemy: Simulate Platform pressing Left
  -> enemy: Set Platform vector X to clamp(self.platform.vectorX,-15,800)

that? LoS.capx

Oh right, I think the jittering is caused by the fact that when you set angles to a negative value, c2 converts it to a 0-360 range.

so, as soon as you rotate counter clockwise past 0 degree it will go to 360 then it's clamped to 15...

So basically you have a sequence of values like that (if isMirrored is true and you have a steady 60fps which gives you a 1/60=0.017 for the value of dt) :

frame 1: 0

frame 2: clamp(0-120*0.017,-15,15) = -2.04

-> converted to 357.96

frame 3: clamp(357.96 - 2.04,-15,15) = 15

... ... ...

and it will go back to 0 as long as you're jumping

So yeah using your RotateTo variable is a good idea (:

And for the dt... Basically to understand how things work, look at how the values evolve when using it.

dt is the time between the previous and the current frame.

in a 60fps game,

<font face="Courier New, Courier, mono">dt = 1/fps = 1/60 = 0.01666666666</font>

(dt is the "second per frame" so spf = 1/fps :D )

let's simplify to 0.017

If you add dt to a value every frame:

<font face="Courier New, Courier, mono">0.017+0.017+0.017+..... </font>

After exactly one second, which is 60 frames, the value will be equal to

<font face="Courier New, Courier, mono">60*1/60 = 1</font>

in a 30 fps game, after one second, which is 30 frames, you'll get

<font face="Courier New, Courier, mono">30*1/30 = 1</font>

So basically, in whatever fps you are, the succession of addition will all reach 1 after one second.

if you add 5*dt, the value will reach 5 after one second

so basically, if you

<font face="Courier New, Courier, mono">set X to self.X + 5*dt </font>

you add 5px to X every one second, so you move your object at exactly 5px per second

It works the same with angle:

<font face="Courier New, Courier, mono">set angle to self.angle + 5*dt </font>

will rotate at 5 degree per second.

that's the holy magic of dt in a nutshell =)

Oh cool (: Thanks Ash

WebFont display correctly on preview, but after an export I get a default font instead.

Works fine on firefox, seems like a chrome-only bug (didn't test IE or Safari though)

Here is my simple testing capx

Chrome-WebFont.capx

As well as an export

Don't use the same sprite for rotation and platforming. Because of collision issue, when your sprite is rotated 15 degree one corner will touch the ground.

Then you set it to 0 degree it goes back in fall mode. Probably creating some wiggling.

You should then do something like setting another sprite to follow your platform sprite. I usually set the platform behavior on my collision box only and then set the eye candy graphics of the character on another sprite that doesn't handle collision.

Let's call it "PlayerSkin"

(You'll have to put your mirroring logic to the PlayerSkin instead by the way)

Global number JRotSpeed = 120  // in degree per second
Global number JAngleLimit = 15  //Limit of jump rotation angle

Player: On Jump 
  -> PlayerSkin: set rotSpeed to PlayerSkin.isMirrored ? JRotSpeed : -JRotSpeed

Player: On Fall 
  -> PlayerSkin: set rotSpeed to PlayerSkin.isMirrored ? -JRotSpeed : JRotSpeed

Player: On Landed 
  -> PlayerSkin: set rotSpeed to 0
  -> Player: set angle to 0

Every Ticks:
  -> PlayerSkin: Set Angle to Clamp(Player.angle+rotSpeed*dt,-JAngle,JAngle)

mouse button is down -> add 5*dt to power

will progresively add 5 to power per second so 1 per 0.2 seconds

System: set scroll X to scrollX+100*dt

Cool Thanks (:
