so I’ve been trying to get a larger painting program working on the raspberry Pi and I was using a different method in the past (FBO) but at the time that wasn’t working like I wanted it to regarding coloring so I switched to this method using setbackgroundauto
this program works perfectly on my computer (mac 10.14.6)
but seems to not work like I want it to regarding painting onto the screen
so I boiled it down to its simplest form in order to post on here
again when I run this on my computer it works as I would expect a circle gets painted onto the screen when I pressed the mouse left button
and when I press the right button it clears that painting
//--------------------------------------------------------------
**void** ofApp::setup(){
ofSetBackgroundAuto( **false** );
ofBackground(25,100,0);
}
//--------------------------------------------------------------
void ofApp::draw(){
if (ofGetMousePressed(OF_MOUSE_BUTTON_RIGHT))
{
ofBackground(25, 100, 0);
}
if (ofGetMousePressed(OF_MOUSE_BUTTON_LEFT))
{
ofDrawCircle (mouseX,
mouseY,
35);
}
}
when I run this on my RPI instead of drawing onto the screen when I press the mouse button it shows a black background
any help would be greatly appreciated
while the larger drawing program partially works on the Pi getting the painting aspect working is pretty key
