Questions from a "dummy" - page 30

Silent:

It is unclear why it works at all.

The correct example is at the bottom of the page

There is also a search first, and redrawing - I saw somewhere that it's better to be safeguarded.

// Don't beat me, I'm learning it myself.

Haven't really looked into it, but it seems to be pretty normal code at first glance.

Silent:

I have highlighted errors, because of which the code does not seem to work. Compare your code to the one in the sample by the link.

Maybe I'm blind, but where exactly are the errors?

Interesting:
I don't understand it but the code seems fine at first glance.

In my post it is highlighted in red - there are no values for chart id, anchor point, anchor angle (what is it for, if we don't rotate the picture?), coordinates.

And I thought I was the beginner)))) This is a function. Values are transferred to it.))

Where do the values come from?

From anywhere. External parameters, global variables, local variables. Or you can write values at once.

Example:

Create_BMP_Label(0,TS_bmp_nm,TS_bmp_pth,ANCHOR_RIGHT_UPPER,CORNER_RIGHT_UPPER,x,y+50);

In my post, in the code marked red - no values for chart id, anchor point, anchor angle (what for, if you don't rotate the picture?), or coordinates.

1. About Id - there should be no values there (as I understand it is expected to be default 0), and what is written in the commentary is most likely "for yourself".

2. About Angles Binding - Binding goes to a particular corner of the graffiti (left-top, right-top, bottom-right and bottom-left). By specifying these parameters we determine what corner the object is anchored to.

This code will create a LABEL at the bottom-right corner

ObjectCreate(0,"Demo",OBJ_LABEL,0,0,1.0);
ObjectSetInteger(0,"Demo",OBJPROP_TIMEFRAMES,OBJ_ALL_PERIODS);
ObjectSetInteger(0,"Demo",OBJPROP_CORNER,CORNER_RIGHT_LOWER);
ObjectSetInteger(0,"Demo",OBJPROP_ANCHOR,ANCHOR_RIGHT_LOWER);
ObjectSetInteger(0,"Demo",OBJPROP_XDISTANCE,3);
ObjectSetInteger(0,"Demo",OBJPROP_YDISTANCE,1);
ObjectSetString(0,"Demo",OBJPROP_FONT,"Times New Roman");
ObjectSetInteger(0,"Demo",OBJPROP_FONTSIZE,8);
ObjectSetInteger(0,"Demo",OBJPROP_COLOR,Tomato);
ObjectSetInteger(0,"Demo",OBJPROP_SELECTABLE,false);
ObjectSetString(0,"Demo",OBJPROP_TEXT,m_text);

And this one will display the same object but in the left-bottom corner

ObjectCreate(0,"Demo",OBJ_LABEL,0,0,1.0);
ObjectSetInteger(0,"Demo",OBJPROP_TIMEFRAMES,OBJ_ALL_PERIODS);
ObjectSetInteger(0,"Demo",OBJPROP_CORNER,CORNER_LEFT_LOWER);
ObjectSetInteger(0,"Demo",OBJPROP_ANCHOR,ANCHOR_LEFT_LOWER);
ObjectSetInteger(0,"Demo",OBJPROP_XDISTANCE,3);
ObjectSetInteger(0,"Demo",OBJPROP_YDISTANCE,1);
ObjectSetString(0,"Demo",OBJPROP_FONT,"Times New Roman");
ObjectSetInteger(0,"Demo",OBJPROP_FONTSIZE,8);
ObjectSetInteger(0,"Demo",OBJPROP_COLOR,Tomato);
ObjectSetInteger(0,"Demo",OBJPROP_SELECTABLE,false);
ObjectSetString(0,"Demo",OBJPROP_TEXT,m_text);

As many of you have already understood, only two lines have changed - these

ObjectSetInteger(0,"Demo",OBJPROP_CORNER,CORNER_LEFT_LOWER);
ObjectSetInteger(0,"Demo",OBJPROP_ANCHOR,ANCHOR_LEFT_LOWER);

Not pincially, it will draw in normal mode if the values are correct. In render mode, there will probably be problems with BMP-graphics (I'm about 90% sure).

[Anatoli Kazharski]

From global variables (highlighted in red).

Create_BMP_Label(0,TS_bmp_nm,TS_bmp_pth,ANCHOR_RIGHT_UPPER,CORNER_RIGHT_UPPER,x,y+50);

From global variables (highlighted in red).

Initialization - inside the function, values - from global? Hmm.
