algorithm - Movement in Java games without pathfinding -

-

let's want have object move along set path between points a, b, , c repeatedly throughout game, based on variable. now, program in full a* pathfinding, take lot of time , require lot of code wouldn't used full worth. there easier way this? @ moment, idea have have object move set number of pixels in 1 direction, another, another, easy object several pixels off after while. should add none of points directly accessible 1 another, in object have go around walls. appreciated, feel i'm missing obvious here.

i should clarify walls not changing position. remain entire game.

define sequence of points p such that:

  • there no obstacle between 2 consecutive points p[i] , p[i + 1].

  • traveling along sequence of points take b , c.

in other words, you're taking path b c , breaking straight segments. points fixed, won't stray path due floating-point precision.

now can accomplish objective moving object point point in sequence p. move in reverse, iterate on p backward.

python - Pygame screen.blit not working -

in program creating in python/pygame, screen.blit not working. in other programs have made, screen.blit works. error: traceback (most recent call last): file "c:...\main.py", line 46, in <module> screen.blit(sight.image, sight.rect) attributeerror: 'int' object has no attribute 'blit' the error in question caused screen variable being allocated integer instead of pygame.surface() object.perhaps accidentally rewrote variable somewhere? from can make of doing, seems stating position of blit full rect instead of coordinate. when do: screen.blit(sight.image,sight.rect) what program seeing is: screen.blit(sight.image,(sight.rect.x,sight.rect.y,sight.rect.width,sight.rect.height)) i assuming don't intend this. remember rect object consists of position, width , height. to correct code, put (sight.rect.x,sight.rect.y) location goes instead this: screen.blit(sight.image,(sight.rect.x,sight.rect.y)) the .x , .y corres
