You just lost me.

That should keep me busy for a while.

FYI my draft table was a Mealy machine, as output
(next action) depends on input (event) and state.

PS
start using type = 0 and define one table at time...

Note that jumps are not sinus movements, but parabolas (gravity is a force, which causes an acceleration according to Newton). Which are a lot faster and easier to compute

A bugfix

main {
...
if ((kbd & 1)!=0 && feet_on_floor) {dy=4;} 
y = y + dy;
if (!feet_on_floor) 
     {dy = max {-4, dy -1};}
else
     {dy = 0;}
...
}

the jump is height

4 + 3 + 2 + 1 = 10 points

@manuel: That's what i meant. I dind knew the english name....

@ARTRAG: What library is max in?

Quote:

What library is max in?

any fantasy lib :-)

try this:

#define max(A,B) ( (A) > (B) ? (A):(B)) 

@manuel
About falling, my solution approximates very well a parabola,
as the 2nd order derivate is constant and equal to -1
(except for the fact that max speed is limited to -4, in
this case the 2nd order derivate is 0, but can
be interpreted as attrite).

@ARTRAG: fantasy.lib

The jump isn't very high. I'll experiment with it this weekend.

I'm must say it's getting rather mathematical. Thats not my biggest talent I thought it would be more about 'tricks' than FSM and stuff. But its real interesting. I vagely remember Mealy and sorts during my study but I had some other interests back then

About FSM, do not worry, things are much simpler that they seem
Go ahead and you'll see yourself


About jumping higer, try

main {
...
if ((kbd & 1)!=0 && feet_on_floor) {dy=5;} 
y = y + dy;
if (!feet_on_floor) 
     {dy = max {-5, dy -1};}
else
     {dy = 0;}
...
}

this gives
5 + 4 + 3 +2 +1 = 15 points

Shouldn't it be: y = y - dy?

Correct! I get confused as screen y are inverted
wrt the standard cartesian plane. Try:

main {
...
if ((kbd & 1)!=0 && feet_on_floor) {dy=-5;} 
y = y + dy;
if (!feet_on_floor) 
     {dy = min {5, dy +1};}
else
     {dy = 0;}
...
}

naturally

#define min(A,B) ( (A) > (B) ? (B):(A))

I think that using ( and ) rather than { and } around the parameters of min will reduce the number of syntax errors with at least one

hit!

Is there an alternative for using fgetc() and fgets()? Seems this is not supported by HITECH

I wanted to load the binairy .stg file from vscreen (copy paste with hex-editor is getting irritating).
