// Step 1: Declare a variable to hold the instance ID of an object
int objID;
// Step 2: Check if the instance exists using instance_exists() function
if (instance_exists(obj_enemy)) {
// Step 3: Assign the instance ID of the object to the variable
objID = instance_find(obj_enemy, 0);
// Step 4: Check if the instance ID is valid
if (objID != noone) {
// Step 5: Perform actions using the valid instance ID
// For example, destroy the object
instance_destroy(objID);
}
}
This code in C++ with GameMaker Studio checks for the existence of an object of type obj_enemy
. If it exists, it retrieves its instance ID and performs an action with it, such as destroying the object.
