Hi guys, I’m new to game develop and I have read the tutorials in the wiki. And now I start to make a flappy clone as a beginning to practice.
When I press control I want to make my bird to fly up in 30 degree(angle) and when falling its degree is minus 30. Hope you guys can understand what I am saying and hope my calculation of the angle is not wrong.
The angles should be opposed 
, from the wiki:
Adding a liitle, upward force (angle = -90, 0<damping<1) when Space is pressed and always add a “gravity” force at down-right (angle = 30, damping = 0) or add the gravity one time when scene starts with disipation = 1 could work.
EDIT: -the upward force (to fly up 30º) should be something like: 2sin(30pi/ 180)*gravity = gravity ¬¬
-a little damping as 0.01 works fine
Clickteam’s products have nice angle selector. Perhaps it could be copied to GD?
I have forgotten the trigonometry function, so I can’t understand the function you wrote. Should review my mathematics now XD
About the gravity, should I put 500? I don’t know how game develop count the gravity, but compare to the other game engine, game develop seems to need a little more higher value.
Another question is, what event and condition should I set. I can’t really understand the events explanation in game develop.
technically all you need to do is show that picture from the wiki in the engine at the appropriate time.
Except in CT products, you have also little arrow that you can easily, visually set to specific angle.
that is too fancy
Nothing is too fancy for GD.
