The warning "warning 215: expression has no effect" means that the compiler has detected an expression that has no impact on the execution of the program. This often happens when a line of code performs no concrete action, such as assigning a value or calling a function.
In your code, this error might occur if the compiler doesn’t correctly recognize certain values or if you have a poorly formed expression.
To identify and fix this warning, here are a few checks you can perform:
- Check the value of "INVALID_TEXT_LABEL" : "If INVALID_TEXT_LABEL" is not defined, or if it is incorrectly defined, this could cause the warning.
- Ensure all expressions are correct: Sometimes, a poorly written expression or incorrect use of an operator can trigger this warning.
Here are some suggestions:
- Make sure "INVALID_TEXT_LABEL" is properly defined, for example:
Code:
#define INVALID_TEXT_LABEL -1 // or another appropriate value- Make sure your for loop has an expression that has an effect, such as initializing an array.
Here’s an example:
Code:
#define MAX_SIGNS_ADMIN 10
#define INVALID_TEXT_LABEL -1 // Ensure this constant is correctly defined
new signLabels[MAX_SIGNS_ADMIN];
new Float:signPositions[MAX_SIGNS_ADMIN][3];
public OnGameModeInit()
{
for (new i = 0; i < MAX_SIGNS_ADMIN; i++)
{
signLabels[i] = INVALID_TEXT_LABEL; // Ensure this assignment is valid
}
if (signPositions[0][0] == 0.0 || signPositions[0][1] == 0.0 || signPositions[0][2] == 0.0)
{
printf("error: invalid float values!");
return 0;
}
return 1;
}
