im trying to make a triangle move using drawfillpolygon but it keeps saying there are errors, whats the error?

for a : 420 .. 700 by 5
var x : array 1 .. 3 of int := init (350, 350, 440)
var y : array 1 .. 3 of int := init (130, 180, 130)
drawfillpolygon (x + a, y, 3, 102)
drawpolygon (x + a, y, 3, 103)
delay (50)
drawfillpolygon (x + a, y, 3, 77)
drawpolygon (x + a, y, 3, 77)
end for

you can't add arrays and integers together. Different types.

1)

code:

use code tags

2) http://www.compsci.ca/v2/viewtopic.php?t=461
3) an array of integers is not the same as an integer, only an index of an array of integers can be added to an integer

In your case you had it mostly right but you missed one thing

code:

%you had drawfillpolygon (x+a...) %what you need drawfillpolygon (x(1)+a....)

so what you need to do is add a single element of your array to an integer, not the entire array
