Hi,
For weeks now I have been trying to create a good top-down car physics engine. For a car movement I'm using:
- Car.x = Car.x + (Cos(Car.angle) * Car.speed)
- Car.y = Car.y - (Sin(Car.angle) * Car.speed)
This formula is good for me when I'm driving at low speed (less that 30% of max speed). But when I exceed 30% i would like to change to space movement:
- Velocity.x = Velocity.x + (Cos(Ship.angle) * Ship.acceleration)
- Velocity.y = Velocity.y - (Sin(Ship.angle) * Ship.acceleration)
How can I change it or how can implement between this two movements?
Thx for reply

Store two angles. Store the direction the car is facing and it's travel direction.
When the speed is less that 30% have the travel direction = direction car is facing.
When the speed is greater than 30% make the travel direction lag behind the direction the car is facing.

Yeah, it's not exactly realistic, but UrbanMonk's solution is a pretty good way of doing simple arcade style car handling. If you need something more sophisticated than that, it's likely to get very complicated, very fast (especially once cars start colliding with things).
