Today's progress in TFTF.zip 
Using the racing resources (opengameart's graphics set)
- Flying object : zeppelin
- Car's player : LEFT, RIGHT, UP

Works to do ... a lot of homeworks for this week  
 1. Monitoring           :  street track, dashboard (angle, speed), life, score
 2. Background         :  city and woods
 3. Incoming barrier  :  fence, road barrier, billboard, cliffs, signs, snowman,trees
 4. More control        :  player's speed acceleration
 5. Condition            :   daylight, night, snowy 
 6. Finish line

In fact, curved road has given me more programming problems to solve than a straight road.  
However, "Don't give up", I said to myself.... I still have 4 days  before the next weekend  Big Grin

Nice start! I only had one itsy-bitsy, teeny-weeny, problem... I ran out of road... lol Nicely done!

Progress Day 2
- Distance   ( limited distance to finish line)
- Life           ( display only at the moment )
- Speed       ( press W to accelerate, S to deaccelerate )
- Moving background (city, woods)

   
click the image to zoom in

Works to do 
 1. Incoming barrier : fence, road barrier,
        billboard, cliffs, signs, snowman,trees
        if hit barrier Life = Life - 1
 2. Dashboard : speed
 3. street track

note : since I have only 3 days before this weekend to finish the game, I reduce my scope of work in the "works to do" list.

Moving scenery? Nice touch...

Small suggestion. Two key presses for changing direction. Left and Right. Rather than pressing the Up key to "straighten" the car, perhaps make it that if the Left or Right key is NOT pressed then return the car "cell" to 3? That way you can reserve the Up and Down keys to control the speed etc...

3 days? You have set a time limit? Interesting.

click the image to zoom in

Progress Day 3
- Add background rock music (looping)
- Add sound effect for car's acceleration
- No more KEY_W or KEY_S for acceleration
- LEFT and RIGHT for changing direction and in 0.5 second would return to normal position (cell 3) or "straighten" automatically
- KEY UP to accelerate the car and deaccelerate automatically  .... whaaaat ?   Big Grin
- Add a nice circle Speedometer

Next
- Incoming barriers (fence, dirt etc.) perhaps these are the most challenging to code
- Street / Race Track

Remaining Days to Finish The Game
- 2 days before this weekend .... aaarrrggghhh... I lost a lot of my hairs ....
  I have set a time limit for my personal reason only, so that this project would not be a "Never ending story"  Big Grin

Nice improvements... Clever use of the accelerator... Slows down when you take your "foot" off... Cool...

Deadlines are a good idea... as long as they are realistic... If you think you can finish in two days, cool... Not many people like a "never ending story" but there is nothing wrong with the story being told over several volumes... Like Lord of the rings...

Remember... If you are not having fun, you maybe doing it wrong... lol

Good lick...

Lord of the Rings...mmm... you've just given me an idea to make an old RPG style with the characters from the Lord of the Rings  Big Grin
Thank you for your advice.

Progress Day 4
   
click the image to zoom in
 
- Added moving traffic signs on the left side of the road
- Added moving trees on the right side of the road
- Eight-Shape Road track with player's position along the track
- Press S to silent (music and sound effect)

Next
Only 1 remaining day to finish the game 
- Collision detection with the traffic signs or trees
- Update Life if collision is detected 

Code:
'---------------------------------------
' THE FAST AND THE FURIOUS - DAY 4
'
' Control :
' - movement        : LEFT, RIGHT
' - speed           : UP, DOWN
' - quit            : ESC
' - music,sound off : S
'
' Note :
' This game is just a proof of concept.
' The duration of the game is very short.
' You may extend the length of the road by changing the value of road.length

Agreed... Looking good!

An amusing side note: (well... I thought it was funny...)

That is one powerful car! The race, for me, lasted for less than a minute... But I maxed out my speed to about 84kph but managed to travel more that 1000km... If my math is correct, and it usually is not, that would mean my actual speed would be about 12,000kph... 30 seconds = distance of 1000; 1 minute = 2000; 1 hour = 2000 X 60... as I said, "One powerful car". The only thing missing is the "Flux Capacitor"... Moo Ha Ha Ha....
