java - Player Movement Direction Logic -


consider points , b walls , point o player inside walls.

so o b.

i want player move left when touches rightpoint b. , move right when touches leftpoint a.

the screen being rendered , player position either incremented 5 right direction or -5 left direction.

what tried do: put in if else if statement. if distance between , o zero, player position gets +5 incrementation. if distance between o , b zero, player position gets -5 incrementation. touches wall(say right wall), moves -5 , 5 , again -5 , 5.

i understand why happening not have logic implement this.

code: sorry not post actual code. im on mobile internet. dont have computer internet.

suppose leftwall @ 50, 0 , rightwall @ 550, 0 , player @ 50, 0.

//this being rendered.

if (rightwall - playerpos <=0){     posincrement = -5; } if (leftwall - playerpos <=0){     posincrement = 5; } translatex (playerpos);

if player should between walls, implies left wall should have position lower the player position. player position shuld equal or larger 50 , equal or smaller 550

so correct logic can be

if (rightwall - playerpos <=0){     posincrement = -5; } if (playerpos - leftwall <=0){     posincrement = 5; }
