According to the perspective mapping x axes is probably so to change

You write the code I don't understand your logic, so don't know how to change, you can refer to my own change again

Really thank you! Physical relationship is all right! But my problem is with the x axis displacement Angle theta image, if you can point me to use for statement to draw out the image of syntax errors would be even better! Thank you again for

CodePudding user response:

I figure is not Angle theta and corresponding relation of x axis direction? Theta in the x direction distance between 30 ~ 40 Angle reaches the maximum,

You r in the for loop is to represent the Angle? Not involved in calculating your point of view,

Yes, how to participate in the operation? Do you understand I am now a part of, don't understand is while statement vX overspending: superposition of the cycle of operations, the effect is always added +=? This step can be implemented in the for statement, please? I have been reading recently has not learned while statement or trouble thank you

CodePudding user response:

X axes and Angle, can be directly calculated with a function, if any, do you use a for loop Angle can be achieved, if the x axes and Angle, can't use a function to calculate directly, that would require the two layers of circulation, the first layer cycle point of view, the second loop to calculate the distance x axis under every Angle, I inside the while loop used to cycle to objects fall to the ground, if use a for loop variable is not set, because the uncertain time

Understand, really thank you very much, please!
