camera.setPos

Scripting Issues
1

hi,
i made class that creates tiles in circle around camera (for grass and etc.)
it does some math and uses only camera.getX() and camera.getY().
it works perfect :slight_smile: but when i set camera to pos x>0 y>0 my tiles center appears on coordinates 0,0 and then travels to coordinates x y (looks quite cool when lots of grass moves toward you :smiley: )
so i think that setpos not makes camera in that position but moves it there? is this right? and how should i fix this?

setPos() on the camera, or on any other NodePath, immediately sets the camera to that new position. There is no delay.

If you are seeing such a delay, it might be due to something else within your program that’s implementing it. For instance, maybe you copied code from someone else that moves the camera gradually to a new position and you didn’t realize it.

hmm, you r right :frowning:
there’s something somewhere wrong in the code, maybe there would be a valounteer to dig up that problem :slight_smile:
this is a code for the tiles

class Tile:
        def __init__(self, x, y, size, content):
            tmpsize = size/2
            c = sqrt(2*tmpsize*tmpsize)
            self.x = x
            self.y = y
            self.content = content
            self.bottomLeftX = x - c
            self.bottomLeftY = x - c
            
        def __del__(self):
            if self.content:
                self.content.removeNode()
            
        def distance(self, x, y):
            return sqrt((self.x-x)*(self.x-x)+(self.y-y)*(self.y-y))
        
        def getArea(self):
            return (self.bottomLeftX,self.bottomLeftY) 

class Tiles:
    def __init__(self, contentF, tilesize = 10, distance = 100 ):
        self.tilesize = tilesize
        self.distance = distance
        self.contentF = contentF
        self.curentTileX = 0
        self.curentTileY = 0
        self.tiles = {}
    
    def update(self, posX, posY):
#TODO:   reiktu padaryt kad uzdetu paramsa kur paslinko
#        ir tada is top[ puses pridetu
#        o is kitus nuimtu
        end = self.tilesize/2
        recalc = False
        if (posX + end)<self.curentTileX:
            self.curentTileX = self.curentTileX - self.tilesize
            recalc = True
        if (posX - end)>self.curentTileX:
            self.curentTileX = self.curentTileX + self.tilesize
            recalc = True
        if (posY + end)<self.curentTileY:
            self.curentTileY = self.curentTileY - self.tilesize
            recalc = True
        if (posY - end)>self.curentTileY:
            self.curentTileY = self.curentTileY + self.tilesize
            recalc = True
            
        if not recalc:
            return
        
        posX = self.curentTileX
        posY = self.curentTileY
        for x in range(posX-self.distance, posX+self.distance, self.tilesize):
            for y in range(posY-self.distance, posY+self.distance, self.tilesize):
                if not self.tileExists(x, y):
                    self.add(x, y)
        self.remove(posX, posY)
        
    def add(self, x, y):
        self.tiles['%s' %str((x,y))] = Tile(x, y, self.tilesize, self.contentF(x,y))
    
    def tileExists(self, x, y):
        if str((x,y)) in self.tiles:
            return True
        return False

    def remove(self, posX, posY):
        for tile in self.tiles.keys():
            if self.tiles[tile].distance(posX, posY)>self.distance:
                del self.tiles[tile]

and this is ho i use it:

class Grass:
    def __init__(self, terrain, camera):
        ...
        self.camera = camera
        self.tiles = Tiles(self.plant2)
        ...
    def update(self):
        self.tiles.update(self.camera.getX(), self.camera.getY())

and then jus use grass.update() in mainloop

hey, ran your code and looks good, kinda reminded me of the original DeltaForce 1 shooter (without the shoothing). so I enjoyed it :slight_smile:

Couldn’t understand exactly what it’s not working so I can give it a look…

ok thanks.
give me few more months and it will look like crysis :smiley:

I am watching this topic, so as soon as you post your update I’ll be downloading and checking it out.
Good luck and plenty of inspiration :wink:
