Name:SPS1, Removed[Show more] Type:Subroutine Category:Maths (Geometry) Summary:Calculate the vector to the planet, sun or station and store it inXX15
Context:See this subroutine in context in the source code References:No direct references to this subroutine in this source file
Arguments:YDetermines the object whose vector we are calculating: * 0 = calculate the vector to the planet * NI% = calculate the vector to the sun/space station Other entry points:SPS1+1A BRK instruction
\ --- Mod: Code removed for Elite-A: ------------------>\.SPS1\\ LDX #0 \ Copy the two high bytes of the planet's x-coordinate\ JSR SPS3 \ into K3(2 1 0), separating out the sign bit into K3+2\\ LDX #3 \ Copy the two high bytes of the planet's y-coordinate\ JSR SPS3 \ into K3(5 4 3), separating out the sign bit into K3+5\\ LDX #6 \ Copy the two high bytes of the planet's z-coordinate\ JSR SPS3 \ into K3(8 7 6), separating out the sign bit into K3+8\\ \ Fall through into TAS2 to build XX15 from K3\ --- End of removed code ----------------------------->
