मेरे पास एक एक्सएनए टावर रक्षा के लिए कुछ कोड है। मैंने यह निर्धारित किया है कि दुश्मन (बग) ग्रिड के एक निश्चित तरफ से एक यादृच्छिक पथ पर चला जाता है जब तक कि वह घर (गंतव्य) या घर के किनारे की पंक्ति को हिट नहीं करता।मेरा यादृच्छिक पथ कोड क्यों काम नहीं करेगा?
मैंने इस परियोजना को डीबग किया और बग खींचा और एक विकर्ण (प्रकार) पथ में आगे बढ़ना शुरू कर दिया। यह हर बार एक ही है (यह यादृच्छिक नहीं है)। मैं नहीं करता कि मैं क्या गलत कर रहा हूं। यह कभी-कभी कोड में उस स्थान पर OutOfMemory अपवाद देता है जहां मैंने इसे निर्दिष्ट किया था। मुझे पता नहीं है कि मैंने इसे बहुत अच्छी तरह से समझाया है तो सवाल पूछने में संकोच न करें। ग्रिड एक जंगल से घिरा हुआ है जो ग्रिड का हिस्सा नहीं है, इसलिए जंगल का मतलब यही है।

धन्यवाद! मुझे अब एहसास है कि बहुत बेवकूफ था – Detinator10
