Cannot make a static reference...

in Programming Questions • 2 years ago

I am trying to make a battle senario like the ones in RPG's such as final fantasy or pokemon. I am currently in the early stages so i tried to run the code and see how it worked, because i thought it was working. but then i got the error message, :Cannot make a static refference to the non-static method Display() from the type RPG.player.

Please Help!

int gamestate;//state that the game currently is
final static int menu = 1;
final static int battle = 2 ;
int turn;//determines who moves: the player or the enemy
final static int monsterturn = 4; // trolls turn
final static int playerturn = 8;//player's turn
int playerhealth = 1000;
int monsterhealth = 666;
int pattack;//player's attack
int pdefense;//player's defense
int pspeed;// player's speed
int experience;//EXP
int mattack, mdefense, mspeed;//speed, attack, defense
//class for the player
class Player{
int px;
int py;
int prad;
float levelbonus = random(0,5);
Player(){
pattack = 26;//attack (medium)
pdefense = 40;//defense (high)
pspeed = 15;//speed(kinda low)
px = 650;
py = 300;
prad = 20;
}
void Display(){
fill(0,255,42);
ellipse(px,py,prad*2,prad*2);
}
void Attack(){
if(mouseX>250&&mouseX<350&&mouseY>610&&mouseY<660 && mousePressed){
monsterhealth = monsterhealth - pattack + mdefense;
turn = monsterturn;
}
}
}
//monster's attacks.
class Monster{
int mx,my,mrad;
float maction = random (0,100);//to calculate what the monster will do
Monster(){
mx = 100;//x coordinate
my = 50;//y coordinate
mrad = 21;//radius of circly
mattack = 50;//attack powah
mdefense = 20;//defense powah
mspeed = 17;//speed powah
}
void Display(){
fill(190,219,191);
ellipse(mx,my,2*mrad,2*mrad);
}
void Action(){
if(maction <=50){
playerhealth = playerhealth - mattack + pdefense;
turn = playerturn;
}
if(maction > 50){
turn = playerturn;
}
}
}
void setup(){
size(750,750);//325 is center.
}
void draw(){
background(255);
switch(gamestate){
default://The menu is the default
background (0);
text("BLAH", 200,290);

When you created a class, most of the time, you have to create an instance of it, using the new keyword.
Like Player player = new Player(); (add parameters to the constructor if you need). Then you call the methods like: player.Display(); This allows, for example, to have several distinct monsters.
