Is not jumping on small screen sizes...

in Programming Questions • 3 months ago

Hello, i trying a little jump and run. The problem is when i set screensize to displayWidth and displayHeight you can see the box jumping. But when i set width and height to 800x480, you can not see the box jump.

This is my code:

int rgb1,rgb2,rgb3;

float x,y,w,h,i;

nt ltime, ctime;

float etime;

void setup(){

float width=800;

float height=480

float boxwidth,boxheight;

boxwidth=width*0.02;

boxheight=width*0.02;

oben=height*0.35-boxheight;

unten=height*0.7-boxheight;

}

void draw(){

size(800,480);

rgb1=247;

rgb2=234;

rgb3=112;

x=0.7*width;

y=0.5*height;

w=0.05*width;

h=height;

rect(x,y,w,h);

//speed=0.019*width;

//i=i+speed;

velocity=width*0.007;

speed=width*0.01;

ctime = millis();

etime = (ctime - ltime)/10;

ltime = ctime;

i=i+velocity*etime;

float inc = TWO_PI/(width*0.0005);

//a = a + inc;

if(mousePressed==true &&jump==0)jump=1;

if(jump==1)

{

jumc=jumc+1;

if(jumc==15){jump=0;a=0;jumc=0;}

yy2=unten- abs(sin(a)) *width*0.2;

//yy2=unten+sin(a)*210.0;1

rect(i,yy2,boxwidth,boxheight);

a=a+inc;

}

if(mousePressed==false && jump==0){ yy2=unten;a=0;

rect(i,yy2,boxwidth,boxheight);

}

if(i>width)i=0;

}

It is so wrong!
Why are you defining local variables width and height shadowing Processing ones, and why are you calling size() in draw()?

Well, i changed this. But this seem not have anything to do with my jumping problem

Re: Is not jumping on small screen sizes...

I thought, when i draw everything depending on width and height (for example width*0.2) it should work on any screensize.

This sketch is for an android app.

Advice: use the formatting command (Ctrl+T) and show the new version of your code, so we can try.
Note: your jump variable can be a boolean, apparently.
And you can check boolean variables as:
if (mousePressed)
or
if (!mousePressed)
instead of using == true or == false.
Probably unrelated to your problem, but can help in having a code easier to read, so to fix.

int rgb1,rgb2,rgb3;

float x,y,w,h,i;

nt ltime, ctime;

float etime;

void setup(){

size(800,480);

float boxwidth,boxheight;

boxwidth=width*0.02;

boxheight=width*0.02;

oben=height*0.35-boxheight;

unten=height*0.7-boxheight;

}

void draw(){

rgb2=234;

rgb3=112;

x=0.7*width;

y=0.5*height;

w=0.05*width;

h=height;

rect(x,y,w,h);

//speed=0.019*width;

//i=i+speed;

velocity=width*0.007;

speed=width*0.01;

ctime = millis();

etime = (ctime - ltime)/10;

ltime = ctime;

i=i+velocity*etime;

float inc = TWO_PI/(width*0.0005);

//a = a + inc;

if(mousePressed==true &&jump==0)jump=1;

if(jump==1)

{

jumc=jumc+1;

if(jumc==15){jump=0;a=0;jumc=0;}

yy2=unten- abs(sin(a)) *width*0.2;

//yy2=unten+sin(a)*210.0;1

rect(i,yy2,boxwidth,boxheight);

a=a+inc;

}

if(mousePressed==false && jump==0){ yy2=unten;a=0;

rect(i,yy2,boxwidth,boxheight);

}

if(i>width)i=0;

}

This is my code. On 800x480 you can't see the box jump, when it's displayWidthXdisplayHeight the box is jumping.

It looks good on my Samsung Galaxy S (1920 x 1080), doesn't work on Samsung S Plus (800x400).

I don't believe that is a running code!

nt instead of int
variable oben is undeclared, etc.

Also, it's unformatted. Lack of <CTRL> + <T>.

Sorry, it is just a snippet from my code.

oben=height*0.35-boxheight;

unten=height*0.7-boxheight;

rgb1=247;

rgb2=234;

rgb3=112;

x=0.7*width;

y=0.5*height;

w=0.05*width;

h=height;

rect(x, y, w, h);

//speed=0.019*width;

//i=i+speed;

ctime = millis();

etime = (ctime - ltime)/10;

ltime = ctime;

i=i+velocity*etime;

float inc = TWO_PI/(width*0.0005);

//a = a + inc;

if (mousePressed==true &&jump==0)jump=1;

if (jump==1)

{

jumc=jumc+1;

if (jumc==15) {

jump=0;

a=0;

jumc=0;

}

yy2=unten- abs(sin(a)) *width*0.2;

//yy2=unten+sin(a)*210.0;1

rect(i, yy2, boxwidth, boxheight);

a=a+inc;

The problem is that you computed an inc value that happened to work correctly in one size, but not in the other. The value was too big, I think.
I made something making more sense (is it?), and fixed also the computation of yy2, that should depend on height, not on width!

Copy code

int rgb1, rgb2, rgb3;
float x, y, w, h, position, oben, unten, velocity, a, yy2;
int ltime, ctime;
float etime;
float jumc, inc;
boolean jumping;
float boxwidth, boxheight;
int MAX_INCR = 15;
void setup() {
size(displayWidth, displayHeight);
//size(800, 600);
// These don't change over time and are already global, so can be moved safely here
boxwidth=width*0.02;
boxheight=width*0.02;
oben=height*0.35-boxheight;
unten=height*0.7-boxheight;
rgb1=247;
rgb2=234;
rgb3=112;
x=0.7*width;
y=0.5*height;
w=0.05*width;
h=height;
inc = (PI / width) * w / MAX_INCR;
println(w + " " + inc);
}
void draw() {
background(0);
rect(x, y, w, h);
//speed=0.019*width;
//i=i+speed;
velocity=width*0.007;
ctime = millis();
etime = (ctime - ltime)/10;
ltime = ctime;
position += velocity*etime;
//a = a + inc;
if (mousePressed && !jumping) jumping = true;
if (jumping)
{
jumc += 1;
if (jumc == MAX_INCR) {
jumping = false;
a = 0;
jumc = 0;
}
yy2 = unten- abs(sin(a)) * h * 2.1;
println(yy2);
//yy2=unten+sin(a)*210.0;1
a += inc;
} else {
yy2 = unten;
a = 0;
}
rect(position, yy2, boxwidth, boxheight);
if (position > width) position = 0;
}

Now the box is not making a half sinus curve, it jumps up (within a sinus) and when it is up it falls straight down.

Then change the code...
Using sin() is quite wrong, anyway. Trajectory should be parabolic.

Why is the box not jumping?

In your example it does.

Re: Is not jumping on small screen sizes...

You made a an int. So when adding a small increment, it doesn't change.

Re: Is not jumping on small screen sizes...

Those bundled operator & assignment have built-in cast conversions.

Even though inc is a float, the result is downgraded to int when the assignment to a takes place!

For any other place else, Java would outright refuse to downgrade a data-type!

Well, the box is still jumping different far on different screen sizes.

I don't know why. Here it works perfect, you can change the screensize and it seems to jump similar.

Re: Is not jumping on small screen sizes...

Ok, i found something out.

The full game has 46 levels, each one is called via a function. In the main loop i have this:

textSize(textsize);

text("Level: "+level+

" Levelscore: "+punktelevel+

" Score: "+punkte, h15, w30);

(will show level, points on the top of each level).

When i delete this lines, the box has the same behavier on fullscreen and 800x480. When the lines are in the main loop on fullscreen, the distance is much further.

Also i had shown some stars (svg)...same than above

Re: Is not jumping on small screen sizes...

@ PhiLho your example works perfect on any screensize. Please try http://www.openprocessing.org/sketch/103796 and change to fullscreen. You will see the different. Maybe processing is to slow?

The class box is for jumping.
