hi
problem when call function with more one parameter.Below code for example

thank's
___________________________________________________________________________
function main{
level_load("test.wmb");
video_switch(7,32,2);
fps_max=70;
while(1){
wait(1);
text_func(100,100,0);//problem point
}
}

text test_txt{
flags=visible;string="this is a test";
}
function text_func(&posx ,&posy, &vis){
while(1){
test_txt.pos_x=posx;
test_txt.pos_y=posy;
if(vis==0){test_txt.visible=off;}
else
{test_txt.visible=on;}
}
}

Mind that when using '&' as a sufix in combo with the parameter, that it must be adressed as vector. Thus when declaring this, you must make sure that you declared it as a vector or sort like

hi
but i can not understand.please tell me more

tnx

use
function text_func(posx ,posy, vis)
for Var's and
function text_func(VECTOR* vec1 ,VECTOR* vec2,vis)
for Vectors

I can't confirm that Vadim647 his solution is correct since I don't know LC that well but I think I need clair something out about it.
Variables (var) can hold data which are mostly numbers.
Which data it can store, depends on the way you declare it.
-Scalar type:
var speed = 10;
-Array type:
var speed[5] = {0, 10, 30, 50, 70}; // you can adress each value by calling the corresponding index.
-Vector type:
var direction[3] = 200,100,20; // mostly vectors are used for x,y and z dimension
-And more types ...

Anyway, what I ment with my explanation is something the manualy can explain nicely

Quote:

---

// quoted from the 3dgs A6 manual
function vector_add2(&sum,&v1,&v2)
{ // calculate the sum of two vectors
sum[0] = v1[0] + v2[0];
sum[1] = v1[1] + v2[1];
sum[2] = v1[2] + v2[2];
}

var vector1[3] = 1,2,3;
var vector2[3] = 4,5,6;
var vector3[3];
...
vector_add2(vector3,vector1,vector2); // vector3 now contains 5,7,9

---

Thus, when using a text, you mostly won't be using vectors to adress them but just via scalars. Simply put, you don't need a & for putting through a position for a text since I assume you didn't adressed it as a vector here

thank u "frazzle" very much.
i think parameter when call function is variable but i know must use by array(vector)

tnx
