Snippet to convert World 3D Coordinates into 2D Screen Relative to the Window:

Spoiler: SAMPFUNCS Opcode 0B55 but in Float Format

{
    pMultY - 6@v - returns the window height multiplier relative to the game screen(feed a dummy variable pointer if not used)
    pMultX - 5@v - returns the window width multiplier relative to the game screen(feed a dummy variable pointer if not used)
    pScreen - 3@v - returns 3@ 4@ - the Converted Window Screen Coordinate
    pCoords - 0@v - gets 0@ 1@ 2@ - feed the world 3D coordinates here

    Example:
        29@ = 1012.5234 // X pos
        30@ = 2942.2132 // Y pos
        31@ = 240.2123 // Z pos
        0AA5: call 0x70CE30 num_params 6 pop 6 bFarClip 0 bNearClip 0 pMultY 27@v pMultX 28@v pScreen 25@v pCoords 29@v // Convert GlobalXYZ To WindowScreenXY
        0AD1: show_formatted_text_highpriority "%f x %f" time 2000 25@ 26@
}
0AA5: call 0x70CE30 num_params 6 pop 6 bFarClip 0 bNearClip 0 pMultY 6@v pMultX 5@v pScreen 3@v pCoords 0@v // Convert GlobalXYZ To WindowScreenXY
