im tryna index it properly it looks awful

private void graphPanel_Paint(object sender, PaintEventArgs e)
        {//List<PointF> pointsToDraw = new List<PointF>();
            
            
            NoHorizontalAcceleration instanceGraphing = new NoHorizontalAcceleration(Convert.ToDouble(storeStartingElevation.Text), Convert.ToDouble(angleOfProjection), Convert.ToDouble(startingVelocity), Convert.ToDouble(verticalAcceleration));
            instanceGraphing.NoHorizontalAccelerationCalculation();
            List<PointF> pointsToDraw = instanceGraphing.drawingGraphLogic(instanceGraphing._timeOfFlight, instanceGraphing._equationForXDisplacement, instanceGraphing._equationForYDisplacement);
            //pointsToDraw null only here and it shouldnt be 13/04/23 //isnt now 14/04/2023
            
            Graphics graphics = e.Graphics;
            Pen pen = new Pen(Color.Black, 5);
            
            for (int i = 0; i < pointsToDraw.Count; i ++)
            {
                if (i ++ == pointsToDraw.Count)
                {
                    
                    graphics.DrawLine(pen, pointsToDraw[i] , pointsToDraw[i]);
                }
                graphics.DrawLine(pen, pointsToDraw[i],pointsToDraw[i++] );
            }
        
        
        
        }

okay, so what exactly are you trying to do and what "isnt working"?

BambiAriaOP•2y ago

yeah thats indexed really bad I assure u its not that bad in the code pointsToDraw has values and im tryna just the drawline to actually draw for me and its just not like no errors or anything just not showing up on my panel

Pobiega•2y ago

have you set a breakpoint? to verify oh dear god uhm

 if (i ++ == pointsToDraw.Count)
                {
                    
                    graphics.DrawLine(pen, pointsToDraw[i] , pointsToDraw[i]);
                }
                graphics.DrawLine(pen, pointsToDraw[i],pointsToDraw[i++] );

 if (i ++ == pointsToDraw.Count)
                {
                    
                    graphics.DrawLine(pen, pointsToDraw[i] , pointsToDraw[i]);
                }
                graphics.DrawLine(pen, pointsToDraw[i],pointsToDraw[i++] );

this is.... what the fuck

BambiAriaOP•2y ago

yeah

Pobiega•2y ago

i++ actually modifies the value of i, fyi

BambiAriaOP•2y ago

oh shit ;-; how did I not see that

Pobiega•2y ago

so if you just want i+1, type i+1 😛

BambiAriaOP•2y ago

theres a lot wrong here I promise you to check theres values in pointsToDraw? or that graphics.DrawLine runs?

Pobiega•2y ago

to check pointsToDraw

BambiAriaOP•2y ago

well i changed my ++'s to + 1's where they should be and now ive got an error but in this case I think thats progress yep ive fixed the error still no drawing tho

Pobiega•2y ago

¯\_(ツ)_/¯

BambiAriaOP•2y ago
