Query about setdrawtarget and map collision

SteveZX81

One of my many projects I'm working on is a game that looks like its running on a ZX Spectrum, but I have something that I don't seem to grasp (that's not new with me) my main loop is thus

loop
clear()
setdrawtarget(screen)
drawmap()
setdrawtarget(framebuffer)
drawimage(screen,200,5,3.5)
collide()
updatesprites()
drawsprites()
update()
repeat

and if I run that, the player - map collision does not work at all. (btw collide is simply a function that tests for map collision and moves the player down if there is none)

yet if I comment out these two lines
setdrawtarget(screen)
setdrawtarget(framebuffer)

then map collision works and my little guy doesn't fall through the ground.

What's the reason it's not working with setdrawtarget?
(yes, I am fully aware than yet again the answer is going to be simple and make me look a fool. so be it)

Thanks folks

@SteveZX81 collidemap()
or detectmapcollision(sprite)

SteveZX81

my collide() function is

function collide()
col = detectmapcollision(player)
if !col then player.x += 2 endif
return void

yeah, as simple as it gets.

i can share my project if you want its still very basic but it might have what your looking for, its got a sprite with collison?

What about moving the collide function above the other 2? (that you said it works when they are //)

Tried that already and it was the same but thanks anyway.

Thanks but that really would only be helpful if its map collisions and you are using setdrawtarget? :)

I think that this may be related: https://fuzearena.com/forum/topic/722/moving-maps/9. I will take a look later

Pianofire mate, it's really not that important it's only a minor project I'm tinkering with.
