December 18, 2002 03:02 PM
i use nehe basecode for my aps, but in my latest rts engine that i have been working on since this summer i have a weird problem.
Everything thats happening with my Camera class goes alot faster if i move my mouse, it''s very strange, and i can''t find the problem?
any ideas?

Nothing I can think of just from the problem alone. Try posting your camera class/input code.

here is the camera class.
Camera.cpp
Camera.h

It sounds as if you''re using the ''wait for message then do something'' type message loop. For example, the scene will only be rendered when the window gets a message ( your mouse cursor creates one for every pixel it moves ). The only doubt I have about this explination is that NeHe''s tutorials run in a non-delayed message mode.

thats the strange part =)
the fps is the same wether i move my mouse or not! =(

thnx mate =)
you led me to the error, i hade put the checkkeys in the messagehandler loop, so when i moved my mouse there was a message being handled and the keys checked again =)
thnx again..

Glad I could help 
Hmm while we are on the topic, would you happen to have any idea on how to switch between delayed and realtime message modes? For example, Unreal Ed has a realtime preview mode that constantly draws the scene, and if you cut it off, it only updates when your mouse moves, ect.
