[SOLVED] How do I make a triangle?

[Zebra]

Hey I am really new to applets, we are making them in class and we are suppose to create a house in the night with blinking stars. I know how to do everything, but make a triangle for my roof. I know how to make a triangle in regular java, but not one for an applet.

So how do you you make an triangle in an applet?

I think there is one in the java 2d package

Sorry, but what is that/ and where can I find it.

Is there just a code on how to make one?

like here is how to make a rectangle in a Java Applet:

Code:

setBackground(Color.black);
page.fillRect(0, 175, 300, 50);

why dont you create two classes, one will be the applet, the other will be JPanel, and in the applet create an instance of the JPanel class and add it to the applet. then in the JPanel use the paint functions to draw just like drawing normally in java.

Sorry, I don't understand how to do that. But is there a code on how to make a triangle like there is to make a rectangle? If so can you give me it. Thanks, sorry I don't understand, but I am only in programming I.

Code:

setBackground(Color.black);
page.fillRect(0, 175, 300, 50);

there are no functions that would draw a triangle for you, however you can use the polygon method in graphics to make any shape you like

heres how it works

Code:

int[] xPoints = {100,50,150};
int[] yPoints = {100,200,200};
g.drawPolygon(xPoints, yPoints, 3);

theres also fillPolygon in case you wish to color it in. You can find all the drawing methods here

i notice ur setting the background color to black, make sure you set the draw color to something else cuz by defaults its black.

Thanks everybody. I just drew lines to make a triangle roof. Here is the code:

Code:

//Roof
        page.setColor (Color.white);
        page.drawLine (MID+1, TOP+1, MID-70, TOP+50);
        page.setColor (Color.white);
        page.drawLine (MID+1, TOP+1, MID+70, TOP+50);
