So I have a video new members can’t attach files but in short my problem is.
I coded it to sense orange objects use the example renaming things in it

event checkPurple = event();
event checkGreen = event();
event checkOrange = event();

void hasPurpleCallback() {
Brain.Screen.setFont(mono40);
Brain.Screen.clearLine(1, black);
Brain.Screen.setCursor(Brain.Screen.row(), 1);
Brain.Screen.setCursor(1, 1);
Eye.takeSnapshot(Eye__PURPLE_CUBE);
if (Eye.objectCount > 0) {
Brain.Screen.print(“Purple Object Found”);
} else {
Brain.Screen.print(“No Purple Object”);
}
}

void hasGreenCallback() {
Brain.Screen.setFont(mono40);
Brain.Screen.clearLine(3, black);
Brain.Screen.setCursor(Brain.Screen.row(), 1);
Brain.Screen.setCursor(3, 1);
Eye.takeSnapshot(Eye__GREEN_CUBE);
if (Eye.objectCount > 0) {
Brain.Screen.print(“Green Object Found”);
} else {
Brain.Screen.print(“No Green Object”);
}
}

void hasOrangeCallback() {
Brain.Screen.setFont(mono40);
Brain.Screen.clearLine(5, black);
Brain.Screen.setCursor(Brain.Screen.row(), 1);
Brain.Screen.setCursor(5, 1);
Eye.takeSnapshot(Eye__ORANGE_CUBE);
if (Eye.objectCount > 0) {
Brain.Screen.print(“Orange Object Found”);
} else {
Brain.Screen.print(“No Orange Object”);
}
}

but when I put it in my robot it does not see it can someone please help

Are your color signatures working? I have never used the objectCount attribute, so can’t say if that is reliable or not. Other than that, your functions look good.

3

Im using Orange, Green, and Purple the colors of the tower takeover cubes

4

I don’t use vexcode, but what is the Eye__PURPLE_CUBE object, and have you set up the colour signatures in the V5 vision utility yet?

5

Im not sure exactly but the Eye is what I named the sensor

6

It may be that you haven’t defined “PURPLE_CUBE” and need to either hard code it or set it up in the vision sensor software (may be built into vexcode, I don’t use it)

You may find it helpful to review examples from the links to vision sensor help that I found for this post: I need help with the vision sensor - #3 by weilin

Also, this: Vision Sensor config - objectCount inconsistent - #7 by jpearman

how do I upload files

If you mean your source code, then you include it in your post surrounded by the [code] ... [/code] tags. Or if you mean vision sensor signatures, then there is a utility for that: Vision sensor setup

i ment on the reply thing like when you type a reply

Yes, that’s what @weilin meant too - copy your program and paste it into a reply, including [code] before it and [ /code] (without the errant space) after it.
