How to layer drawing on the top...Plz help!!!!!!

in Programming Questions • 1 year ago

Hi,

I have a problem doing a hero drawing over a 2D pattern which generates by a single pattern unit...

It would be a huge huge huge favour if anyone could help me, Thank you!!!!!

//draw my hero

void drawDoraemon()

{

Draw Hero code here

}

//draw pme unit of a pattern

//and position it according to x and y parameters

//draw surprising pattern

void drawPatternUnit(int xxx, int yyy)

{

pushMatrix();//isolates transformations in memory



//transformations happen in reverse

translate(xxx, yyy);//move the Pattern by this much



Pattern drawing code here



popMatrix();//done isolating memory



}

void drawSuprisingPattern()

{



//draw pattern unit horizontal line down many times

for(int j=0; j < 4; j++)

{

//code we want repeated



//entire horz line of units

//draw pattern unit across this many times

for(int i=0; i < 4; i++)

{

//code we want repeated

drawPatternUnit(i*100 , j*100);

}

}





}

So it's basically what I have got so far...

I know I've miss something to make my hero drawing to be overlaying the pattern drawing.

I am not too sure what you are asking, but if you want your hero to be drawn in front of your background pattern, just draw it after you drawn the pattern.

I try but it doesn't work. My main problem is that my draw hero function and the pattern function are two separate functions. When I repeat the draw pattern function (which indicates as the void drawSuprisingPattern() function), the pattern automatically layer on the top and cover my hero. I hope that would clarify my problem.

When you draw something, it is always on top of everything, that has been drawn before. So you have to do it like PhiLho wrote, draw the pattern and then draw the hero. If you draw the pattern again, just draw the hero again too.
Without seeing your whole code, it's hard to tell, what you are doing wrong. Your draw-function should look similar to this:

void draw(){
background(0);
drawSuprisingPattern();
drawDoraemon();
}
