How would I be able to make text show up when the player goes on the ellipse in state 0?

Use dist to detect if the guy is near the ellipse

Then set a boolean showText to true

Use if(showText) text("ghggg", 111,222);

to display the text

Also you can either set showText to false when he moves away or after a certain time period:

if(millis()-startTime>5000) showText=false;

Set startTime to millis() where you set showText to true

Nathan101

I'm not very good with boolean, could you type what I should put please!

Chrisir

before setup():

boolean showText = false; 
int startTime; 

in draw():

if(showText) text("ghggg", 111,222);
if(millis()-startTime>5000) showText=false;

Use dist() to detect if the guy is near the ellipse - Then set showText to true and set startTime to millis() :

if(dist(linkX,linkY,...,....) < 30) {
    showText = true;
    startTime=millis();
}

Chrisir

I made some additions

Nathan101

thanks

Chrisir

this calls for a class or for arrays: !!!!!!

PImage Enemy1Down;
PImage Enemy1Up;
PImage Enemy1Right;
PImage Enemy1Left;

PImage Enemy2Down;
PImage Enemy2Up;
PImage Enemy2Right;
PImage Enemy2Left;

PImage Enemy3Down;
PImage Enemy3Up;
PImage Enemy3Right;

in theory, treat each enemy like a ball and give it a movement vector

xSpeed, ySpeed and move it.

When it bounces into a wall say xSpeed-=xSpeed; etc.

Check enemy against player with dist()

Nathan101

please give me an example of what I should do! please!

Chrisir

before setup

    Enemy3PosX=55; 
    Enemy3PosY=155; 

in draw

    Enemy3PosX+=Enemy3SpeedX;

Nathan101

could you write everything I have to do so I can understand completely what I need to do?

Nathan101

Just write all the code

Chrisir

did you get the concept?

you move an enemy by adding something to its position, so it moves...?

you need to add to Enemy3PosXand posY....

for all enemys

Nathan101

But how would I make it move randomly in different directions?

Chrisir

int direction = int(random(4));

switch (direction) {

case 0:
  //north
  Enemy3SpeedX=0;
  Enemy3SpeedY=-1;
  break; 

case 1:
  //east
  Enemy3SpeedX=1;
  Enemy3SpeedY=0;
  break; 

case 2:
  //south
  Enemy3SpeedX=0;
  Enemy3SpeedY=-1;
  break; 

case 3:
  //west
  Enemy3SpeedX=-1;
  Enemy3SpeedY=0;
  break;
}

Nathan101

What variables will I have to create?

Chrisir

??

Whatever you like.

Those are all variables: the enemy pos, the speed etc. create them before setup or better make an enemy class
