When you want to obtain the height of a TEXT object you can do it as follows: Code: int height = myText.font.dy; Terrain tutorial using Shade-C amBx-Plugin - use amBx in GameStudio 3D Tower Defence

If the text contains multiple lines, you can use this function:

Code:

function txt_height(TEXT* text)
{
	int i = 0, linecount = 0;
	for(i = 0; i < text->strings; i++)
	{
		linecount += *(text->pstring)[i]->pad;
	}
	return text->font->dy * linecount;
}

Because it is unofficial it might change in future versions of 3dgs). Some examples "line1\nline2\line3" -> pad[0-3] = 3 "line1" -> pad[0-3] = 1 This is faster then checking every character of a string for a new-line. Because linecount is an integer, only the 4 first bytes of pad are copied(that's what we want, becuase there the line count of the string is located)
