I'm stumped with a custom movement...

[KLiK-iT]

Hi Guys, I'm a bit stumped here. I've tried to duplicate the airplane movement in this game for another type game I'm trying to build for over a week now. I just can't seem to get it right! Would anyone have any idea how the movement of the plane is done? Am I thinking into this to much? Is it more simple as it seems? An example would be great.

Thank you,

One solution is to start with a constant declining angle. Lets say every 100ms (I'd use the old timer delta but it's up to you). When the player hits a button the added angle should be more than the declining. That's at least a linear direction delta that might be enough for your purposes. I have an example but in this case that dynamic is a whole game so I cant share it. However I'd be willing to help out if you are or get stuck on something.

I'm really not getting what you're saying. Would it be to much trouble to make a simple example of this type movement? The angle of the plane is one issue and how is the speed set to increase and decrease as the mouse is pressed or released? It's a really nice custom movement going on in that game and very smooth. Any help would be appreciated!!

It's really very, very simple...

+ Repeat while mouse button is down
-> Plane: Subtract ClimbRate from YVelocity

+ Always
-> Plane: Add Gravity to YVelocity
-> Plane: Add YVelocity to YPos
-> Plane: Set Y position to YPos
-> Plane: Set angle to ATan2(0-YVelocity( "Plane" ), XVelocity( "Plane" ))
-> CoinsEtc: Set X position to X("CoinsEtc") - XVelocity("Plane")

pardon my mediocre explanation KLiK-iT. Plane angle would simply be added upon mouse click. If you'd like acceleration, deceleration and air resistance that's part of your custom movement. Sadly that does take some time to do right. In this case you might be better off doing a plausible plane movement first and then go on making more features later.

I think muddys example is good. If you need a simple screen centered solution that is the way to go.

Wow MuddyMole, Thank you very much for the example as this will work. I will study it and learn something from this. It's perfect! Learn something new every day. Thanks again to both of you!
