Can't do more than one pfread on a line?

[BenMcLean]

I get a syntax error when I try to do more than one pfread in an if-then statement. What's going on with that and how can I fix it?

I think bB is just too simple to understand that.

try this

  if joy0up && heroY > _Edge_Top && !pfread(mytemp1, mytemp2) then if !pfread(mytemp3, mytemp2) then heroY = heroY - 1

Another method is to nest one if-then statement into another. Whatever works!

 set smartbranching on
 set romsize 4k


 scorecolor = $0E
main
 if !pfread(0, 0) then if !pfread(1, 1) then score = 999
 COLUBK = $4E
 drawscreen
 goto main

I must have made a typo when I had already tried what you were suggesting before I posted because the method you suggested works now. Thanks. I finally got playfield collision prevention working, albeit with the rule that all horizontal surfaces in my playfield must be at least 2 blocks long to prevent moving through them vertically. (since I'm only pfreading the edges of the player's box facing the direction the player is moving in, and the player's box is wider than a single playfield block)

Now the tricky part is going to be collision prevention and pathfinding for the enemies. ^_^
