No Text refresh

[Mr_Blues]

Hello, i am a beginner and a newbie with hollywood. just i want to make a quiz with hollywood, i take the DaCoolQuiz code and mdify it with my questions. But for longer questions i had to use a larger display and larger buttons, now with the effect that the text in the questions and answerbuttons overwrite the previous text with no refreshig. The irst question you can read in a normal way, but u the secnd question you have only garbage on the screen. What is wrong?
Here the modfied code:

Many thanks for your help

If you change the display size and make it larger, you also need to adapt all other calls to functions which are related to the display size, i.e. all functions which draw something might need an adjustment in their position or size arguments.

[Bugala]

Just giving example:

suppose you have hardcoded numbers, for example: (imaginary commands)

displaytext(200, 300) (- this would be x and y spot)


If this program is normally run on 800x600 screen, it means it would be about starting from about location 1/4th of screen from right, and be displayed starting from middle of screen from height point of view.

If you change display to 1920 x 1200 and still use these same x and y numbers on this command, it would now be displayed at about 1/10th from right and about 1/4th from top of screen from height point of view.

To make it look the same with 1920 x 1200 you would need to change the numbers into about:

displaytext(500, 600)


However, this would still not look the same, since yo would still need to change the font size, as if the font size would be, say 30, then 30x30 pixels in 800x600 is about 1/500th of the size of whole screen, while 30x30 in 1920 x 1200 is only rougly 1/3000th of a screens size.



When changing the numbers, you could use variables to define the position where to put them at.

For example, as i pointed out the 200,300 location with 800x600 would be about 1/4th and 1/2th (=middle), hence you could make it this way:

Screenwidth=1920
screenheight=1200

text_x = screenwidth/4
text_y = screenheight/2

textdisplay(text_x, text_y)

this way you would only need to change the screenwidth and screenheight variables, and text would always be displayed at same location (of 1/4th width, 1/2 = middle height), regardless of the screensize.
