math floor problem

[ysj4]

        local wX, wY = getScreenFromWorldPosition(bX, bY, bZ + 0.35)
        local sX, sY = math.floor(wX), math.floor(wY)

bX, bY, bZ its a pedBone position

problem its a with wX idk why

Hello ysj4,

did you know that if (bX, bY, bZ + 0.35) are outside of your GTA SA game client screen then the getScreenFromWorldPosition function does return false? If you want to know about a more generic way to get a blip position in the camera-orriented direction then take a look at this thread in which I responded last year:

The reason for this issue is very simple: you cannot see any world position on your screen that is outside of your game client window. Thus you should not expect the getScreenFromWorldPosition function to return anything that you cannot see!

How about you don't draw nametags that are not visible on screen? Since the 3D projection is a frustum which has a bottom plane (far-clip) too far players do not get a screen position either.

Or just use the function I have linked for you. It does not return false in the far-clip case.

HINT: you need to enable OOP in your MTA resource to use the get_screen_coordinates function!

HINT: the get_screen_coordinates function does return relative values; you have to multiply them with the screen dimensions to get pixel values.
