Hi good afternoon.

How can you build a collisons counter here?

Thank you.
greeting

```  x=50
y=50

COLUBK=200

main

if collision(player1,player0) then COLUBK=\$28 else COLUBK=200

COLUPF=214

COLUP0=128
COLUP1=64

player0:
%00011100
%00011000
%00011000
%00100000
%01011010
%01111100
%00100100
%00010000
%00011000
%00111100
%00011000
end

player1:
%00011100
%00011000
%00011000
%00100000
%01011010
%01111100
%00100100
%00010000
%00011000
%00111100
%00111100
end

player0x=x
player0y=y

player1x=80
player1y=30

drawscreen

if joy0right then x=x+1
if joy0left then x=x-1
if joy0up then y=y-1
if joy0down then y=y+1

goto main
```

This should be quite simple.

You can add another variable where you currently have have y=50 add a new variable. For example:

i=0 : rem Used to count collisions.

where you test for collision in this line.

` if collision(player1,player0) then COLUBK=\$28 else COLUBK=200`

`if collision(player1,player0) then i=i+1`

That would be a simple way to do it.

I hope that points you in the right direction.

Joe
